실험 절차

Addition of phosphonyl chloride to a mixture of thiosemicarbazide and methoxyacetic acid at 60°-95° and working up of the product yields 5-amino-2-methoxymethyl-(1,3,4)thiadiazole, m.p. 177°-179° (from water). When this compound is diazotised and treated with cuprous bromide 5-bromo-2-methoxymethyl-(1,3,4)-thiadiazole results and reaction of this bromo compound with zinc dust in acetic acid at room temperature yields 2-methoxymethyl-(1,3,4)-thiadiazole, m.p. 30.5°-32°.
