Application of 37687-18-6<\/a>, The chemical industry reduces the impact on the environment during synthesis 37687-18-6, name is 1-(1-Methyl-1h-pyrazol-4-yl)-ethanone, I believe this compound will play a more active role in future production and life.<\/p>\n

Method 31 Synthesis of 2-bromo-1-(6-methyl-3-pyridyl)ethanone (Intermediate 45) To a solution of R-12 (10 g, 79.3 mmol) in MeCN (200 mL) at 0 C. is added N,O-dimethylhydroxylaminehydrochloride (8.5 g, 87.2 mmol), EDCI (18.2 g, 95.2 mmol), 1-hydroxybenzotriazole (3.2 g, 23.8 mmol) followed by triethylamine (20.5 mL, 158 mmol) and stirred at room temperature 15 h. The reaction mixture is partitioned between water and EtOAc. The collected organics are dried with anhydrous Na2SO4, filtered, and concentrated in vacuo to give I-43 (12 g) m\/z 170.0 [M+H].<\/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-(1-Methyl-1h-pyrazol-4-yl)-ethanone, other downstream synthetic routes, hurry up and to see.<\/p>\n
