Reaction Steps

To a solution of 2-phenoxyisonicotinaldehyde (378 mg) in tetrahydrofuran (4 ml), 0.228 ml of diiodomethane and 3.8 ml of methyllithium (1.0M diethyl ether solution) were added under ice-cooling, and the reaction solution was stirred at the same temperature for 1 hour. To the reaction solution was added 10% aqueous citric acid, and the mixture was extracted with ethyl acetate. The combined organic layers were washed with a saturated saline solution and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue obtained was purified by silica gel column chromatography (eluent: hexane/ethyl acetate (98:2-50/50)) to afford the title compound as a yellow oil.
