To a solution of 1-phenylethylamine (10.45 g) and triethylamine (14.4 ml) in dichloromethane (100 ml) was added dropwise acetic anhydride (9.0 ml) at room temperature. The mixture was stirred at room temperature for 5 hr. The reaction mixture was poured into ice water (200 ml) and extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate and the solvent was evaporated. The obtained residue was left standing at room temperature for 3 hr. The obtained crude crystals were washed several times with hexane to give the title compound (14.0 g) as white crystals.
