Versuchsvorschrift
At 0, methyl chloroformate (4.6 g, 48 mmol) was added dropwise to a solution of 2-(3-chloro-phenyl)-ethylamine (5.0 g, 32 mmol) and Et3N (6.4 g, 64 mmol) in DCM (100 mL). After the addition, the mixture was stirred at room temperature for 0.5 hour. The organic layer was washed with water (3×30 mL), 1N HCl (20 mL) and brine (30 mL), dried over anhy. Na2SO4, filtered and concentrated in vacuo. After vacuum drying, the title compound was obtained (6.49 g, 95%) as a white solid. MS: 214.1 (M+H+).
