To a stirred solution of 49.2 parts of 2-methoxy-5-methylbenzenamine and 270 parts of methylbenzene were added dropwise 22.5 parts of 2-chloroacetyl chloride while cooling (ice-bath) at 10°-20° C. Upon completion, stirring was continued for 1.50 hours at room temperature. 200 Parts of water were added. The organic phase was separated, washed with water, dried, filtered and evaporated. The oily residue was crystallized from 2,2'-oxybispropane. The product was filtered off and dried, yielding 28.2 parts (66%) of 2-chloro-N-(2-methoxy-5-methylphenyl)acetamide; mp. 83.9° C.
