Procedure
A solution of 5-methylisoxazole-3-carbonyl chloride (0.41 g., 2.83 mmole) in dioxane was added to a solution of 4-amino-6,7-dimethoxy-2-(1-piperazinyl)quinazoline (0.82 g., 2.83 mmole) in dioxane. The mixture was treated as described in the previous example to give the title compound having a m.p. of 271°-273° C. with decomposition.
