Procedure
2.75 mol of hydrazine hydrate was added to a solution of 0.275 mol of ethyl ester of 4-(4-chloro benzyloxy) benzoic acid (X) in 300 ml ethanol. The reaction medium was reflux-heated for 48 hours. After cooling, the expected product was separated by filtration and recrystallised from ethanol.
