Reaction Steps

A solution of (3,4-dichloro-phenyl)-acetic acid methyl ester (44.7 mmol) and hydrazine (447 mmol) in ethanol (100 mL) was stirred at 80° C. for 18 h. After it was cooled to room temperature and concentrated in vacuo, the crude product was purified by crystallization in ethanol to give (3,4-dichloro-phenyl)-acetic acid hydrazide (43 mmol).
