実験手順

A mixture of compound (1) (1.0 g) and sodium hydride (0.11 g), in DMF (20 ml) was stirred for 20 minutes at RT under argon flow. Then, 2-isocyanato-propane (0.27 ml) was added dropwise over 30 minutes and the reaction mixture was allowed to stir at RT overnight. The solvent was evaporated and water added. The residue was filtered, washed with water and diethyl ether, and recrystallized from 1,4-dioxane. The precipitate was filtered off and dried, yielding 0.95 g (85.1%) of N-[4-[(4-cyano-phenyl)amino]-6-[(2,6-dichlorophenyl)methyl]-1,3,5-triazin-2-yl]-N′-(1-methylethyl)-urea (compound 6, mp. 267-268° C.).
