Reaction Steps

0.5 g of N-(1,3-dimethyl-4-ethoxycarbonyl-5-pyrazolesulfonyl)-N'-(4,6-dimethyl-2-pyrimidinyl)thiourea is suspended in 20 ml of methanol, followed by adding 0.2 g of N-bromosuccinimide while stirring at --4° C. to -5° C. The reaction mixture is stirred at the same temperature for 25 minutes. The separating crystals are filtered, and washed with methanol. Recrystallization of the crystals from acetonitrile yields 0.4 g of the title compound as colorless
