The procedures of Example 3 were repeated except that the starting material was 50 ml of an acetone solution containing 8.9 g (51 mmol) of 2-difluoromethoxy-6-methyl aniline, to which 10.5 g (77 mmol) of potassium carbonate and 7.0 g (62 mmol) of chloroacetyl chloride were added. As a result, 12.0 g of 2-chloro-2'-difluoromethoxy-6'-methylacetanilide was obtained. It had a melting point of 85° to 86° C.
