Reaktionsschritte
By the procedure of Example 5, 0.4 g of the product of Example 4 was reacted with 0.41 g of phenyl(4-methyl-6-methoxy-1,3,5-triazin-2-yl)carbamate and 0.24 g of "DBU" in 10 ml of p-dioxane. The isolated crude solid was purified by slurry-washing with 10 ml of warm acetonitrile to yield 0.3 g of the subject compound; m.p. 198°-200° C.
