Reference of 3994-50-1<\/a>, The chemical industry reduces the impact on the environment during synthesis 3994-50-1, name is 1-Methyl-4-nitro-1H-pyrazole, I believe this compound will play a more active role in future production and life.<\/p>\n

Under hydrogen (1 atm), to a solution of compound 15-b (1.0 g, 7.87 mmol) in ethanol (15 mL) was added 10% Pd-C (0.2 g). The mixture was stirred at 25 C. for 18 hours, and then filtrated, the filtrate was concentrated under reduced pressure, the residue was purified by silica column chromatography (petroleum ether:ethyl acetate=1:1) to give red oil 15-a (700 mg, yield: 92%).<\/p>\n

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Methyl-4-nitro-1H-pyrazole, other downstream synthetic routes, hurry up and to see.<\/p>\n
