Procedure
4.03 g of 4-chloro-6-cyclopentylmethoxy-7-methylcarbonyloxy-quinazoline are suspended in 70 ml of isopropanol and 1.95 g of 3-chloro-4-fluoro-aniline are added. The reaction mixture is refluxed for two hours under a nitrogen atmosphere. After cooling to ambient temperature the light-coloured precipitate formed is suction filtered, washed with a little isopropanol and dried in the air.
