Yield: 79%

Reaction Conditions:

with hydrazine hydrate in methanol;water at 20; for 5 h;Cooling with ice;

Steps:

3.2.3. General Procedure for the Synthesis of Acyl Hydrazides 3a-3k
General procedure: To a stirred solution of esters 2a-2j (70 mmol) in MeOH (30 mL) cooled in an ice-water bath was added dropwise 80% aqueous hydrazine hydrate (6.26 g, 100 mmol). The resulting solution was stirred at room temperature (2a-2b or 2d-2j), or reflux (2c), until the completion of reaction as indicated by TLC analysis (typically within 5 h). The reaction mixture was evaporated on a rotary evaporator to give a residue, which was purified by column chromatography through a short silica gel column to yield 3a-3k after trituration with n-hexane if possible.
