Acetyl chloride → HCID 21320431, compound

Participants

Reaction Steps

3.2 ml of acetyl chloride dissolved in 10 ml of anhydrous benzene is added dropwise at 0° - 5° C in the course of one hour, with stirring, to a solution of 12.7 g of 4-phenoxy-N-(3,4-methylenedioxybenzyl)-aniline and 6 g of N-ethyl-diisopropylamine in 100 ml of anhydrous benzene. The whole is subsequently heated to room temperature and stirred for a further 8 hours. The precipitated N-ethyl-diisopropylamine-hydrochloride is separated by filtration; the filtrate is washed with 10% sodium carbonate solution and then with water. After drying of the organic phase by means of sodium sulphate, the benzene is distilled off in vacuo, and the residue recrystallised in hexane to obtain 4-phenoxy-N-acetyl-N-(3,4-methylenedioxybenzyl)-aniline, M.P. 75°- 76° C.
