HCID 19781550HCID 19781550, compoundYield 44%

Procedure

Sodium hydride (0.19 g; 7.8 mmoles) was added to 50 ml of methanol, and 2.1 g (7.8 mmoles) of 2-piperidino-4-chloromethyl-5-methoxycarbonylpyrimidine was added at room temperature. The mixture was stirred for 3 hours. After the solvent was evaporated, water was added to the residue and the mixture was extracted with ethyl acetate. The ethyl acetate layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography to give 0.90 g (yield 44%) of the desired product as a white solid.
