Piperidine → 4-(2-Butynyloxy)-5-fluoro-6-piperidinopyrimidine

Participants

Reaction Steps

Into 3 ml of ethanol was resolved 0.3 g of 4-(2-butynyloxy)-6-chloro-5-fluoropyrimidine, 0.38 g of piperidine was added therein, and the mixture was stirred for 7 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 0.37 g of 4-(2-butynyloxy)-5-fluoro-6-piperidinopyrimidine (hereinafter, referred to as Compound (2)).
