참여 물질

반응 단계

A solution/suspension of 2-chloro-6-(methyloxy)-3-nitropyridine (65.7 g, 348 mmol) in 2M ammonia in MeOH (500 ml, 1000 mmol) and aqueous ammonia (500 ml, 348 mmol) was stirred at 65° C. for 18 h. The reaction was cooled down and the solid filtered off and washed with water (2×100 ml). The solid was dried in the vacuum oven at 40° C. overnight to afford the product as a bright yellow solid (52.14 g, 84% purity by NMR, 74%).
