Reaktionsschritte

To a solution of compound 4-(2-amino-6-phenyl-pyrimidin-4-ylamino)-2-chloro-phenol (0.5 g, 1.6 mmol) in dry dimethylformamide (10 mL) was added 4-(N,N-dimethylamino)pyridine (0.39 g, 3.2 mmol) at 0° C. with stirring under nitrogen atmosphere. To this was added freshly prepared succinyl chloride (0.62 g, 4 mmol). The mixture was then stirred at 80° C. for 20 hours. After completion of the reaction the mixture was diluted with water (75 mL), the solid separated was filtered off, washed with cold water (200 mL) and dried. The solid was purified further by column chromatography using petroleum ether-ethyl acetate to give the desired product as a light brown solid.
