실험 절차

A solution of 1.00 g of N-[4-(4-piperidinomethyl-2-pyridyloxy)-cis-2-butenyl]-4-(acetylthio)butyramide [prepared as described in step (a) above] in 10 ml of methanol was added to a mixture of 0.48 g of 28% w/v methanolic sodium methoxide and 5 ml of methanol, whilst ice-cooling, and the mixture was stirred at the same temperature for 20 minutes. At the end of this time, 0.28 g of 4-chloropyrimidine was added to the mixture and the mixture was heated under reflux for 2 hours. The solvent was then removed by evaporation under reduced pressure, and water was added to the resulting residue, which was then extracted with ethyl acetate. The solvent was removed from the extract by distillation under reduced pressure, and the residue was purified by column chromatography through silica gel, using a 1:9 by volume mixture of ethanol and chloroform as the eluent, to give 0.65 g (yield 60%) of the title compound as an oil.
