Participants

Reaction Steps

To a solution of (S)-(−)-1-phenylethylamine (121 g) and triethylamine (168 ml) in dichloroethane (1200 ml) was added dropwise acetyl chloride (78.2 ml) over 1 hr under ice-cooling and the mixture was stirred at room temperature for 2 hr. The reaction mixture was poured into water (1000 ml) and the organic layer was separated. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated to give the title compound (143.4 g) as pale-yellow crystals, m.p.=99-101° C.
