use | intermediate of clotrimazole. |
Production method | Use o-chlorobenzoic acid and ethanol to esterify with sulfuric acid or p-toluenesulfonic acid to generate ethyl o-chlorobenzoate, and then Condensation with phenyl magnesium bromide (Grignard reaction) to obtain (2-chlorophenyl) diphenylmethanol magnesium salt, which is hydrolyzed with sulfuric acid to obtain (2-chlorophenyl) diphenylmethanol, and then chlorinated with thionyl chloride to obtain the product. |
