Phenethylamine → 2-Chloro-N-phenethyl-acetamide

Participants

Reaction Steps

5 ml of triethylamine were added to a solution of 3.64 g of phenethylamine dissolved in 35 ml of methylene chloride, and the mixture was stirred, whilst ice-cooling. 2.63 ml of chloroacetyl chloride were then added dropwise to the mixture over a period of 5 minutes, after which it was stirred for 30 minutes whilst ice-cooling. The reaction mixture was then concentrated by evaporation under reduced pressure, after which ethyl acetate was added to the residue. The ethyl acetate solution was washed, in turn, with water, with a 5% w/v aqueous solution of sodium bicarbonate, with 10% w/v aqueous hydrochloric acid and with a saturated aqueous solution of sodium chloride. It was then dried, and the solvent was distilled off. The residue was recrystallized from a mixture of ethyl acetate and hexane, to give 4.96 g of the title compound as pale yellow-brown needles melting at 62°-65° C.
