2-Chloro-4-(N-(2-phenylethyl)anilino)pyrimidine (Reference Example E-3; 270 mg, 0.87 mmol) was dissolved in NMP (2 ml), 4-[3-(N,N-dimethyl)amino-2-hydroxypropoxy]aniline hydrochloride (Reference Example D-1; 222 mg, 0.90 mmol) was added and the mixture heated at 120° C. for 12 hours. The solvent was evaporated, the residue was resolubilized in methanol/ammonia 6M and evaporated again to dryness. The resulting solid was purified by flash chromatography using increasingly polar solvent mixtures starting with DCM and ending with DCM/methanol with 10% ammonia (87.5/12.5). Evaporation of the solvent gave a foam which was triturated in ether to give the title product as a white solid (150 mg, 36%).
