Procedure

4-(3-Fluoropropyl)aniline and 2,6-dichloro-5-fluoropyrimidine (1.5 g) were dissolved in methanol (5 mL) and water (1 mL). The reaction solution was stirred at rt for 3 d. The reaction solution was diluted with water (100 mL) and extracted with ethyl acetate (2×100 mL). The organic layers were evaporated and purified by flash column chromatography (EtOAc/hexanes=¼, ½) to give 2-chloro-5-fluoro-N4-[4-(3-fluoropropyl)phenyl]-4-pyrimidineamine.
