Reaction Steps

A suspension of 1.0 g of N-(2-trifluoromethylbenzyl) sulfonyl-N'-(4,6-dimethoxy-2-pyrimidinyl)thiourea in 20 ml of methanol is cooled at -10°~-5° C., and a solution of 0.12 ml of bromine in 1 ml of methanol is dropwise added to the solution. The temperature of the mixture is gradually raised to room temperature and the mixture is stirred for 2 hours. The crystals are collected by filtration, washed with methanol, dried and recrystallized from acetonitrile to give 0.8 g of the title compound as white crystals.
