3994-50-1, name is 1-Methyl-4-nitro-1H-pyrazole, belongs to pyrazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: 1-Methyl-4-nitro-1H-pyrazole<\/a><\/p>\n

Intermediate 153 (Z)-1-(1-Methyl-4-nitro-1H-pyrazol-5-yl)cyclohept-4-enol To a solution of 1-methyl-4-nitro-1H-pyrazole (1.5 g, 11.8 mmol) and (Z)-cyclohept-4-enone (1.4 g, 13.0 mmol) in dry THF (30 mL) under nitrogen cooled to -78 C. was added dropwise a solution of lithium hexamethyldisilazide (1.0 M in THF, 30 mL, 29.5 mmol). The reaction mixture was allowed to warm to -40 C. and stirred for 90 min. Saturated aqueous ammonium chloride solution (30 mL) was added (dropwise initially) and the mixture was allowed to warm to room temperature and extracted with EtOAc (150 mL). The organic layer was washed with water (30 mL), washed with brine (20 mL), separated, dried over MgSO4 and concentrated under reduced pressure. Purification via silica gel column chromatography (20-25% EtOAc) gave (Z)-1-(1-methyl-4-nitro-1H-pyrazol-5-yl)cyclohept-4-enol as a tan oil (1.37 g, 49%).<\/p>\n

The synthetic route of 3994-50-1 has been constantly updated, and we look forward to future research findings.<\/p>\n
