After stirring at room temperature for 1 hour, the reaction mixture was washed with 1 N hydrochloric acid, sodium hydrogen carbonate solution and saturated sodium chloride solution, dried over anhydrous magnesium sulfate and concentrated. The crude crystals (2.9 g) were recrystallized from ethanol to give N-(3-chloro-4-trifluoromethoxyphenyl)-1-methylcyclopropanecarboxamide (2.6 g). M.P., 101°-102° C.
