288-13-1<\/a>, The chemical industry reduces the impact on the environment during synthesis 288-13-1, name is 1H-Pyrazole, I believe this compound will play a more active role in future production and life.<\/p>\n

General procedure: 1-benzyl-4-chloro-3,5-dimethyl-1H-pyrazole. To a 16 mL vial containing 1-benzyl-3,5-dimethyl-1H-pyrazole (196 mg, 1.05 mmol) and a magnetic stir bar, 0.7 mL of water and 0.3 mL of ethyl acetate was added. Next, NaCl (123 mg, 2 mmol) was added and the vial was placed in a room temperature water bath to control exotherms. Finally, Oxone (322 mg, 0.52 mmol or 1.05 mmol KHSO5) was added and the vial was capped. The reaction proceeded with continuous and vigorous stirring until no starting material remained as indicated by TLC (1 h). The remaining oxidants were reduced with solid sodium bisulfite until starch iodide paper tested negative. Water (5 mL) was added and the mixture was extracted with 1:1 hexanes\/diethyl ether (3 x 5 mL). The combined organic fractions were dried (MgSO4) and concentrated to yield crude product that was purified by flash chromatography (14 x 1 cm), 9:1 hexane\/ethyl acetate eluent. Pure 1-benzyl-4-chloro-3,5-dimethyl-1H-pyrazole was obtained as a pale yellow oil (215 mg, 93% yield).<\/p>\n
