使用2-Chlorotrityl chloride is used as an intermediate of clotrimazole. It is also used in the preparation of modified trityl nucleosides as inhibitors of P. falciparum dUTPase. In addition, it serves as a protecting group reagent for carboxylic acids forming esters.
製造方法2-Chlorotrityl chloride synthesis: It is esterified with 2-Chlorobenzoic acid and ethanol in the presence of sulfuric acid or p-toluenesulfonic acid to generate Ethyl 2-Chlorobenzoate, which is then condensed with phenylmagnesium bromide (Grignard reaction) to obtain (2-Chlorophenyl)diphenylmethanol magnesium salt is hydrolyzed with sulfuric acid to obtain (2-Chlorophenyl)diphenylmethanol, which is then chlorinated with thionyl chloride to obtain the product.
