Procedure

Into 3 ml of ethanol was resolved 0.3 g of 4-(2-butynyloxy)-6-chloro-5-fluoropyrimidine, 0.45 g of 2-methylpyperidine was added therein, and the mixture was stirred for 5 hours under reflux condition. The reaction mixture was cooled to near room temperature and concentrated. The residue was subjected to silica gel column chromatography to obtain 0.28 g of 4-(2-butynyloxy)-5-fluoro-6-(2-methylpiperidino)pyrimidine (hereinafter, referred to as Compound (1)).
