Benzene → Nonivamide

関与物質

反応手順

58.5 parts of 4-hydroxy-3-methoxybenzylamine hydrochloride, 200 parts of benzene and 200 parts of water were charged into a reaction vessel equipped with a three-one motor the rotational frequency of which is variable and an outlet having a stopper at the bottom portion and stirred. 58 parts of potassium carbonate was added to the mixture and further 54 parts of pelargonoyl chloride was added dropwise to a resultant mixture at room temperature. In this state, the mixture was stirred for 3 hours until the end of the reaction. After the stirring was stopped and the mixture was allowed to stand for 30 minutes, the water layer in the lower layer was discharged from the bottom portion. The residue was distilled under a reduced pressure to remove solvent almost completely, thereby obtaining crude nonylic acid vanillylamide. As a result of quantitative analysis of a slight amount of product by HPLC, the purity of nonylic acid vanillylamide was determined to be 92.1%. The irritant nature thereof to skin, especially, to mucosae was strong.
