反应详情

NH4OH (22 mL, excess) can be added to a solution of 3-cyanobenzene-1-sulfonyl chloride (1.0 g, 4.97 mmol) in acetonitrile (22 mL) and the reaction stirred overnight at r.t. The reaction can be concentrated and the solid obtained washed with water to give 500 mg of product. The water phase can be extracted with AcOEt, dried with MgSO4 anh, filtered and evaporated to give 400 mg of product that can be combined with the solid obtained before (0.90 g, 99%).
