To a solution of (2S)-2-(4-aminophenyl)-4-((1R)-1-phenylethyl)morpholine (7.9 g, 28 mmol) and triethylamine (8.5 g, 84 mmol) in tetrahydrofuran (180 ml) was added acetyl chloride (4.4 g, 56 mmol). The mixture was stirred at room temperature for 2 hours and partitioned between water and chloroform. The organic extract was washed with brine and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure and the precipitated crystals were collected by filtration, washed with isopropyl ether to give N-(4-((2S)-4-((1R)-1-phenylethyl)morpholin-2-yl)phenyl)-acetamide (6.47 g, 71%) as yellow crystals.
