That Hyperlab thread is mostly a discussion of various methods of synthesizing piperonal from piperine  The part that shroomedlalice was referring to is in response to what Zolvox posted:

quote (said: Zolvox)
 
Condensate all gathered in one container and put in refrigerator for 12 hours. The solution became completely transparent, and at the bottom grew white translucent crystals. But they were so small that the young chemist upset and did not conduct any further manipulation
 


Good job, next time better to lead the recording is fixed more carefully what he was doing as something laid. For example, it seems suspicious that the IRS could dissolve 20% KOH and do not specify the volume of solution taken, well, all right, now in effect.

1. Condensate was necessary to extract something, because piperonal solubility in water is 0.2 g per 100 ml of water.

2. You can try other oxidants such as dichromate in sulfuric acid in the presence of sulfanilic acid (protects aldehydes derived from further oxidation), such as making an example here (http://www.chemister.pp.ru/Database/search.dbp?action = synthesis & dbid = 1 & id = 119). Without sulfanilic acid output usually falls at least twice.

as an alternative to permanganate since the yield is approximately doubled when sulfanilic acid is employed to protect the aldehyde   Sulfanilic acid is prepared by heating aniline with an excess of sulfuric acid for four to five hours and is an important reagent in the dye industry  The attached article should clarify matters

Hmmm... Anisealdehyde brominated via HBr perhaps (?) to 4-MeO-3,5-DiBr-Benzaldehyde, followed by the methylation utilizing Na Methoxide formed ala Ullmann w/ NaOH, MeOH, & molsieves. Now THAT'S starting to sound more accessible- both the synths/reagents as well as the starting aldehyde, which is certainly more available than Elemicin. I can see why they call you 'Friendly Stranger', Mr. carl_nnabis...  The halogenation of the 3 & 5 positions on Anisealdehyde seems logical, but I have to ask if you have either a reference or firsthand anecdotal evidence (for example how likely is either 'over-bromination' or only partial bromination of the Anisealdehyde, leaving one with a mix of variously brominated products which would have to be separated from the desired 3,5-DiBr-Anisealdehyde -?). If anything, it would certainly help to lend weight to this particular route indeed being the most 'home friendly'!

And Lugh thanks for pointing out the relevant section in that translated Hyperlab thread, as well as the tips for sulfanilic acid preparation. I'll check out the article you posted over the next few days. 

Thanks everyone for continuing to contribute to this interesting & informative thread!

hmm thought i edited the post to say the reference was not of use, there was a two-step synthesis example where they dichlorinated 4-hydroxybenzaldehyd on position 3 and 5, and some other sources that state this or similiar reactionslike monohalogenation occuring in anisaldehyd on position 3.
There is even a simple fungus who can in occurence of chloride, bromide or iodide salts dihalogenate his own selfmade aromatic aldehydes (mainly 4-OH and 4-MeO benzaldehyde) in a similiar manner first on 3, then on 5. This fungus seemed not to care which of both benzaldehydes, both became 3,5-dihalosubstituted

The not measured melting point was btw above 100° from that precipitate i have made once, and its smell was also noticeable different, it really smelled like someone familiar with anisaldehyd and chlorous smelling stuff would expect it
Nothing like anisaldehyde at all, just a memory of anisaldehyde is left it that stuff, but it had its own smell, i doubt if it would become overoxidized to (dichloro)anisic acid that it still would at all.
But summarized what does this say about if it works or not? just that anisaldehyde reacts tp a solid with way higher melting point before with its own smell that implicates just that my anisaldehyde had get a dichloro substitution without getting oxidized all the way down to anisic acid.
Also possible would be after it got his first chlorine attached, that the other ones will attach opposed to the first, so one would end up with the 3,4,6-tri-MeO mescaline, dont know if that is a good one?

Anyway this would be too much work for mescaline itself, have you considered oxidizing calamus oil yet to asaronaldehyde? the mescaline analogue out of it is a bit potenter too
