Procedure

4-Amino-2,5-dimethylphenol (10.5 g) is added at room temperature to a suspension of sodium hydride (60% dispersion in mineral oil, 3 g) in anhydrous dimethylformamide (300 ml). The reaction mixture is stirred for 30 minutes and 5-bromo-3-phenyl-1,2,4-thiadiazole (18 g) prepared according to Chem. Ber. 1961, 94, 2043 is then added slowly. After stirring for 15 h, the reaction mixture is diluted in ice-water and then extracted with diethyl ether. Drying over magnesium sulphate followed by concentration of the combined organic phases gives the title compound.
