反応手順

In 30 ml of dioxane, there was dissolved 1.16 g. (4 mmole) of 2-piperazino-4-amino-6,7-dimethoxyquinazoline. To the resultant solution was added dropwise 0.45 g. (4 mmole) of cyclopentyl isocyanate at room temperature and the mixture was stirred overnight at room temperature. The precipitated crystals were recovered by filtration to obtain 1.34 g. of the desired product.
