It does actually say 9.5% but on the other hand they claim 95% yield from 100g of safrole, so it has to be 95g. Scrap that decimal point, I have corrected it in the file at my page.
Where did you find the J Pharm Sci article text? In a post at the Hive?
Rhodium, it was actually posted by you.

Thanks for the Brazilian reference. I've noticed that on you page this proceedure is scaled 10x, except for the amount of HCl and water.
