Procedure

To 1.05 g (3 mmol) of ethyl 2-(4-chloro-2-methylphenoxymethyl)phenyl-2-methoxyacetate was added 6 ml of methanol and 0.75 g (15 mmol) of hydrazine monohydrate and stirred at 60° C. for 16 hours. After completion of the reaction, 100 ml of brine was added and extracted twice with 70 ml of dichloromethane. The extract was dried over anhydrous magnesium and concentrated under reduced pressure to give 2-(4-chloro-2-methylphenoxymethyl)phenyl-2-methoxyacetic acid hydrazide (0.93 g, 92.6%) as colorless oil.
