Procedure

To a solution of 2-amino-1-phenylethanonehydrochloride (1a) (1715 mg, 10 mmol) in DMF (20 mL) was added TEA (2.8 mL, 20 mmol). Upon cooling under ice-water bath, methylsulfonyl chloride (0.77 mL, 10 mmol) was added slowly and the reaction mixture stirred at RT for 12 h. The mixture was partitioned between dichloromethane and brine, dried over sodium sulfate and then concentrated in vacuo to give the title compound (2100 mg, 98%) as an off white solid. MS APCI, m/z=214 (M+1). LCMS: 1.19 min.
