Electric Literature of 138786-86-4, The chemical industry reduces the impact on the environment during synthesis 138786-86-4, name is Methyl 4-nitro-1H-pyrazole-3-carboxylate, I believe this compound will play a more active role in future production and life.
Example 12 Benzyl-(2S)-4-(5-{[(4-amino-1-phenyl-1H-pyrazol-3-yl)amino]carbonyl}pyridin-2-yl)-2-methylpiperazine-1-carboxylate A solution of methyl 4-nitro-1H-pyrazole-3-carboxylate (54.0 g, 315.6 mmol), phenylboronic acid (77.0 g, 631.2 mmol), copper(II) acetate (86.0 g, 473.4 mmol) and pyridine (49.9 g, 631.2 mmol) in methylene chloride (600 mL) was stirred at ambient temperature open to air for 48 hours. The reaction was evaporated in vacuo, diluted with 1 L of methylene chloride and filtered through a large plug of silica (washing with 2 L methylene chloride). The solvent was evaporated in vacuo to give methyl 4-nitro-1-phenyl-1H-pyrazole-3-carboxylate confirmed by 1H NMR (CDCl3) delta 8.61 (s, 1H), 7.73 (m, 2H), 7.50 (m, 3H), 4.02 (s, 3H).
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, Methyl 4-nitro-1H-pyrazole-3-carboxylate, other downstream synthetic routes, hurry up and to see.
