Yield:-

Reaction Conditions:

with hydrazine hydrate in ethanol;Reflux;

Steps:

General procedure for intermediates 14

General procedure: Intermediates 14 were prepared by following the knownprocedure [22, 29, 30]. The mixture of ethyl 2-chloroacetate(1 mmol), substituted phenols (1 mmol), and K2CO3(1.2 mmol) in acetonitrile was stirred in refluxing for 2 h(the course of the reactions was monitored by TLC), thenfiltered, and the mother liquid was evaporated in vacuo toafford corresponding substituted ethyl 2-phenoxyacetates,which were then reacted with hydrazine hydrate (80%) toyield substituted 2-phenoxyacetohydrazides 14 in>90%yield.
