Reaction Steps

195 b) To a stirred suspension of 2-methanesulfonylamino-benzoic acid ethyl ester (1.0 g, 4.1 mmol) and cesium carbonate (1.5 g, 4.5 mmol) in acetonitrile (10 mL) was added iodomethane (0.28 mL, 4.5 mmol). The mixture was stirred at room temperature for 18 hours then diluted with dichloromethane (30 mL), filtered through a plug of diatomaceous earth and evaporated. 2-(Methanesulfonyl-methyl-amino)-benzoic acid ethyl ester was isolated as a clear viscous oil (1.08 g, 100%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.90 (d, J=7.7 Hz, 1H), 7.55 (t, J=7.7 Hz, 1H), 7.47-7.38 (m, 2H), 4.38 (q, J=7.0 Hz, 2H), 3.32 (s, 3H), 2.96 (s, 3H), 1.41 (t, J=7.1 Hz, 3H). MS=280 (M+Na)+.
