Title:

ISOPROPYL 3-CHLORO-4-METHYLBENZOATE AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2013/015203

Kind Code:

A1

Abstract:

Provided is isopropyl 3-chloro-4-methylbenzoate, which is a novel substance that is useful as an intermediate for the synthesis of functional polymer materials, agrichemicals, pharmaceuticals, and the like. Also provided is a method for producing the same. Isopropyl 3-chloro-4-methylbenzoate represented by formula (1) is produced by the method whereby 4-chloro-methylbenzoic acid chloride is subjected to nuclear chlorination in the presence of chlorine and a Lewis acid catalyst, the resulting 3-chloro-4-methylbenzoic acid chloride is esterified by isopropyl alcohol, and isopropyl 3-chloro-4-methylbenzoate is produced.
