Microwave assisted synthesis of 2-(4- methoxylbenzoylamido)-5- aryloxymethyl-1,3,4-thiadiazoles
4-Methoxylbenzoyl chloride reacting with ammonium thiocyanate and aryloxyacetic acid hydrazides under phase transfer catalysis at room temperature gives 1-aryloxyacetyl-4-(4-methoxylbenzoyl)-thiosemicarbazides (Ia-m). Compounds Ia-m together with glacial
