A mixture of 0.60 g (2 mmol) of 5-amino-4-(methylamino)-2-[[4-(morpholin-4-yl)phenyl]amino]pyrimidine, 1.23 g (4 mmol) of ethyl 2-(3,5-dichloro-2,6-dimethoxypyridin-4-yl)-2-oxoacetate, and 1 mL HOAc in 20 mL 2-methoxyethanol is heated under reflux for 16 hours. Workup in EtOAc, followed by chromatography on silica, eluting with hexane-EtOAc (3:2), gives 0.55 g (51%) of the title compound (Compound 18): mp (EtOH) 275–276° C.
