YieldReaction ConditionsOperation in experiment
With potassium; In N-methyl-acetamide; Petroleum ether; A mixture of 18.6 g (0.1 mole) of 2-mercapto-5-trifluoromethyl-1,3,4-thiadiazole and 5.6 g (0.1 mole) of powdered potassium hyroxide in 100 ml of absolute dimethylformamide was stirred for 30 minutes. 20.8 g (0.1 mole) of <strong>[13195-50-1]2-bromo-5-nitro-thiophene</strong> were added in a single portion. The mixture was stirred for 3 hours at 50° C, diluted with water and extracted with methylene chloride and after drying the organic phase was evaporated over sodium sulfate. Vacuum distillation gave 24.4 g of crude product of boiling point 160°-163° C/0.3 mm Hg, which was recrystallized from hexane/ethyl acetate (10:1). After further recrystallization ether/petroleum ether (4:3), 17.3 g (55percent of theory) of pure 2-(5'-nitro-thiophen-2'-yl-thio)-5-trifluoromethyl-1,3,4-thiadiazole of melting point 57° c were obtained.
