実験手順

To a suspension of 3-(3-fluoro-4-(piperazin-1-yl)phenyl)-2,6-dimethylpyrimidin-4(3H)-one (0.30 g, 1.00 mmol) and K2CO3 (0.69 g, 5.00 mmol) in CH3CN (15 mL) was added 3-bromoprop-1-yne (0.12 g, 1.01 mmol) and the mixture was stirred at rt for 36 h. The mixture was then filtered, and the filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=1:1) to give the title compound as a white solid (0.15 g, 44%). The compound was characterized by the following spectroscopic data:
