Reaction of aryloxyacetic acid hydrazide or arenedioxydiacetic acid hydrazide with 2-ethoxybenzoy chloride and ammonium thiocyanate under the condition of solid-liquid phase transfer catalysis using polyethylene glycol-400 (PEG-400) as the catalyst yielded the corresponding thiosemicarbazide or bisthiosemicarbazide derivatives of 2-ethoxybenzoic acid in good-to-excellent yield.
