Yield:3920-39-6 100%
Reaction Conditions:
with ammonia in methanol at 50;Sealed tube;
Steps:
A solution of methyl 1-methyl-4-nitro-1H-pyrazole-3-carboxylate 22 (480 mg, 2.59 mmol) in 7Mammonia (in MeOH, 8 mL) in a 25 mL sealed tube was stirred at 50 °C overnight. The solventswere evaporated under reduced pressure to give 1-methyl-4-nitro-1H-pyrazole-3-carboxamide 26(quant) as an off-white solid.
