Procedure

[3-(Methoxycarbonyl)benzyl](triphenyl)phosphonium bromide (930 mg) was mixed with DMF (6 ml), and potassium tert-butoxide (300 mg) was added thereto at 0° C., followed by stirring for 30 minutes. 2-(Morpholin-4-yl)pyrimidine-5-carboaldehyde (300 mg) was added to the reaction mixture, followed by stirring at 0° C. for 1 hour, and stirring again at room temperature for 1 hour. The reaction mixture was concentrated under reduced pressure, and EtOAc and a saturated aqueous sodium hydrogen carbonate solution were then added thereto. The organic layer was dried over Na2SO4 and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/EtOAc) to obtain methyl 3-{2-[2-(morpholin-4-yl)pyrimidin-5-yl]vinyl}benzoate (377 mg).
