실험 절차
A mixture of 5.0 g of 2-difluoromethoxyphenyl-sulfonylisocyanate and 4.0 g of 2-amino-4-tert-butylamino-6-methoxy-1,3,5-triazine is stirred in 60 ml of absolute dioxane for 3 hours at 70°-80° C. After filtration of the hot reaction mixture through active charcoal, 6.9 g of N-(2-difluoromethoxyphenyl-sulfonyl)-N'-(4-tert-butylamino-6-methoxy-1,3,5-triazin-2-yl)-urea, m.p. 213°-214° C., crystallise out on cooling of the solution.
