反応手順
To a solution of 4-nitro-1H-pyrazole (1.13 g, 10.0 mmol) and iodomethane (1.25 mL, 20.0 mmol) in DMF (12 mL), NaH (60% in mineral oil, 0.600 g, 15.0 mmol) was added. The mixture was stirred for 18 h. Water and EtOAc were added. The organic phase was separated, washed with water, dried over Na2SO4, concentrated in vacuo to give 1-methyl-4-nitro-1H-pyrazole as a solid (1.11 g).
