Yield:98021-39-7 81.25%
Reaction Conditions:
with hydrazine hydrate in ethanol at 40; for 3 h;
Steps:
8.2 Step 2: 6-oxo-1H-pyridazine-3-carbohydrazide
[0290] To a stirred solution of methyl 6-oxo-1H-pyridazine-3-carboxylate (800.00 mg, 5.19 mmol) in EtOH (5.00 mL) was added Hydrazine Monohydrate (1.0 mL). The reaction mixture was stirred for 3 h at 40°C. The reaction mixture was allowed to cool down to room temperature. The precipitated solids were collected by filtration and washed with ACN (2x2 mL) to give the title compound as a white solid (650 mg, 81.25%)MS m/z: 155 [M+H]+.
