Reference of 288148-34-5, The chemical industry reduces the impact on the environment during synthesis 288148-34-5, name is 1-Methyl-1H-pyrazole-4-sulfonyl chloride, I believe this compound will play a more active role in future production and life.
General procedure: Allylamine (1.05 equiv) and triethylamine (1.1 equiv) were added in CH2Cl2 to a solution of sulfonyl chloride (1 equiv) in CH2Cl2 (2.5mL/mmol). The reaction was stirred at room temperature for 1 h, then washedwith sat. NH4Cl solution and brine. The organic phase was dried over MgSO4, filtered and concentrated to give the following sulfonylchlorides, which were used without further purification.
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-1H-pyrazole-4-sulfonyl chloride, other downstream synthetic routes, hurry up and to see.
