Procedure

A mixture of 0.66 g (2 mmol) of 5-amino-2-[[4-[2-(diethylamino)-ethoxy]phenyl]amino]-4-(methylamino)pyrimidine, 1.23 g (4 mmol) of ethyl 2-(3,5-dichloro-2,6-dimethoxypyridin-4-yl)-2-oxoacetate, and 1 mL of HOAc in 20 mL of 2-methoxyethanol is heated under reflux for 16 hours. Workup as in 6 above gives 0.59 g (51%) of the title compound (Compound 21): mp (EtOH) 239–240° C.
