Reaction Steps

A solution of 4-amino-N-(3-bromo-4-fluorophenyl)-1,2,5-thiadiazole-3-carbothioamide (130 mg, 0.4 mmol) in dichloromethane (5.2 mL) was treated with methyl trifluoromethanesulfonate (64 μL, 0.6 mmol) followed by N,N-diisopropylethylamine (102 μL, 0.6 mmol) and stirred for 1 h. The reaction mixture was diluted with dichloromethane (100 mL), washed with water (50 mL) and brine (50 mL), dried with sodium sulfate, filtered, and concentrated to give the desired product (133 mg, 98%). LCMS for C10H9BrFN4S2 (M+H)+: m/z=346.8, 348.8.
