Reaction Steps

3.72 g (0.085 mole) of 55% strength sodium hydride in paraffin oil are suspended in 150 ml of absolute tetrahydrofuran and 18.6 g (0.085 mole) of 2-(2-hydroxystyryl)-5-methyl-1,3,4-thiadiazole in 200 ml of absolute hexamethylphosphotriamide are then added dropwise in the course of 1.5 hours at from 0° to 3° C. Stirring is continued at room temperature for 1 hour, after which 11.7 g (0.085 mole) of dibromohydrin are added dropwise. The solution is left to stand at room temperature for 16 hours, after which it is poured onto 1.5 liters of ice water and 0.5 liter of saturated sodium chloride solution. The precipitated solid is filtered off and recrystallized from acetone. 11.8 g (51% of theory) of yellow crystals, of melting point 134°-135° C. are obtained.
