Procedure

To a stirred solution of methyl 3-(pyridin-3-yl)benzoate (190 mg, 0.89 mmol) in anhydrous methanol (1 mL) was added hydrazine (0.07 mL,). The solution was stirred at RT overnight before ethyl ether was added. The solid was filtered and washed with ethyl ether to give 67 mg (35% yield) of 3-(pyridin-3-yl)benzohydrazide as a white solid. An additional 120 mg of the product was recovered from the filtrate. (M+H)+=214.13
