PURPOSE:To obtain the titled compound useful as an intermediate for pharmaceuticals and agricultural chemicals, etc., advantageously in a short time in high yield, by using easily available alpha,alpha,alpha,alpha',alpha'-pentachloro-o-xylene as a raw material and hydrolyzing the material under pressure,. CONSTITUTION:The objective compound is produced by using alpha,alpha,alpha,alpha',alpha'- pentachloro-o-xylene as a raw material and hydrolyzing the material under pressure, preferably 1-10kg/cm<2> (gauge), especially 3-4kg/cm<2> at 100-200 deg.C, preferably 140-150 deg.C using a solvent (especially preferably water or hydrochloric acid). The reaction time is 1-3hr.
