Procedure

To a solution of N-(2-methyl-4-nitrophenyl)benzamide (Example 1099A) (0.38 g, 1.48 mmol) in DMF (2 mL) was added cesium carbonate (1.2 g, 3.68 mmol) followed by methyl iodide (0.12 mL, 1.9 mmol). The reaction mixture was stirred at room temp for 2 hr, extracted with EtOAc, washed with water and brine, dried and concentrated in vacuo to give N-methyl-N-(2-methyl-4-nitrophenyl)-benzamide (0.38 g, 95%). ES-MS (M+H)+=271.
