Procedure

To solution of 4-amino-2-chloro-6,7-dimethoxyquinazoline (0.240 g, 1 mmol) in 10 ml dioxane was added morpholine (0.350 ml, 4 mmol). The mixture was heated at 85° C. for 4 h. After cooling to room temperature, the reaction mixture was diluted with water and solid was precipitated. The resulting precipitate was collected by filtration and washed with water and little amount of methanol and to give A 6,7-dimethoxy-2-morpholin-4-yl-quinazolin-4-ylamine (0.275 g) in 94% yield.
