A solution of 4-(3-isopropyl-1,2,4-oxadiazol-5-yl)piperidine hydrochloride (2.0 gm, 0.008369 moles) and diisopropylethylamine (2.78 gm, 0.0215 moles) in dichloromethane (30 ml) was added to an ice-cooled solution of 4,6-dichloro-5-methylpyrimidine (2.1 gm, 0.001295 moles) in dichloromethane (10 ml) and the reaction was stirred at 27° C. for 2 h. The reaction mixture was diluted with dichloromethane and washed with water and brine, dried over sodium sulfate and evaporated under reduced pressure. The crude was purified by flash column chromatography (silica gel, 15% ethyl acetate in hexane) to afford the title compound as a white solid (43% yield).
