Reaction Steps

3-Methylaniline (1 g, 9.3 mmol) in 2N aqueous sodium hydroxide (30 mL) was treated with chloroacetyl chloride (0.82 mL, 10.27 mmol) dropwise at room temperature as a solution in dichloromethane. After 18 hours, the reaction mixture was quenched with water and the layers separated. The organic phase was washed with an aqueous solution of 1N HCl and dried over MgSO4, filtered and the filtrate concentrated under reduced pressure to provide 1.3 g (76%) of the title compound as a white solid. 1H NMR (300 MHz, CDCI3) δ 2.35 (s, 3H), 4.20 (s, 2H), 7.00 (s, 1H), 7.22 (m, 1H), 7.35-7.45 (m, 2H), 8.15 (br s, 1H); MS (DCI/NH3) m/e 201 (M+NH4)+.
