Usage：It is used to synthesize methyl p-sulfonyl chlorobenzopropionate. Aromatic sulfonyl chloride is an important pharmaceutical intermediate(synthetic sulfonamide drugs), which has a broad application prospect. The synthesis of p-sulfonyl chlorobenzopropionate by methyl phenylpropionate is simple and practical. The technical scheme adopted in the invention for the above purposes is as follows: the synthesis method of methyl sulfonyl chlorobenzopropionate is firstly esterified with phenylpropionate, then sulfonated with chlorosulfonic acid, then hydrolyzed, the solid is precipitated, dried, recrystallized and refined as the product.
Key words: 3-Phenylpropionic acid methyl ester, Methyl benzenepropanoate, pharmaceutical intermediate
