I gave this a go tonight. Don't be to hard on me, this is only my first synthesis!
Anyways I followed Jon's method using this amounts below:
100ml / 105 grams GAA
88.4 grams NaBR
80.1 grams H2SO4
73 grams Safrole
I first started by vacuum distilling my Chinese sassafras oil to yield a clear water white oil which really refracts light, hopefully safrole! I then made up my 40% GAA solution by dissolving all the NaBr in 100ml of GAA. A lot of the salt didn't dissolve but that's ok isn't it?
I then proceed to slowly drip the H2SO4 into the solution. It heated up a small bit and there was some HBr fumes evolved but they were easily controlled by placing the flask in a cold water bath while stoppering it. It was then placed in the freezer for approx. 20 minutes to cool the solution.
Once it was cooled, I swirled the flask to break up the small layer of NaBR that had settled on the bottom of the flask. I then added the safrole all at once. I fucked up a bit here. I hadn't as much distilled as I thought, so I only added 58grams of Safrole rather than the calculated 73 grams. Will this fuck up the reaction?
I now have it left in the freezer for 24hours and will crash with water and extract with DCM as was outlined earlier.
Now I just have to go make some Methylamine while I wait for my NaI to arrive. Hopefully I get something from this! Fingers crossed!
