反応手順

By the procedure of Example 4, 0.3 g of the sulfonamide prepared in Example 3 was reacted with 0.29 g of phenyl(4-methoxy-6-methyl-1,3,5-triazin-2-yl)carbamate and 0.15 g of "DBU" in 10 ml of p-dioxane. After stirring two hours at room temperature the solution was diluted with about 75 ml of water and acidified with concentrated hydrochloric acid (red to litmus paper). Following filtration, the residue was washed with water (2×20ml) then with ether (1×20ml) and suction-dried to give 0.15 g of the subject compound; m.p. 140°-146° C. NMR (CDCl3): δ2.6(d,6H,SCH3, OCH3); 4.1 (S, 3H, CH3); 4.9(S, 2H, CH2); 7.4-7.7(m, 4H, Ar+NH); 8.3(d, 1H, Ar).
