Procedure

To a suspension of 4-chloro-3-nitropyridine (2 g, 12.6 mmol) in dichloromethane (15 mL) was cautiously added methyl amine (25% solution in water, 10 mL, 63 mmol). The reaction mixture was heated to 40° C. After stirring for 1 h, the mixture was poured into water (20 mL), and the precipitate was collected by filtration and dried in vacuo to afford the title compound (1.9 g, yield 98%) as a yellow solid. LC-MS (ESI) m/z: 154 (M+1)+.
