실험 절차

To a solution of 0.250 g (1.566 mmol) of 4,5,6,7-tetrahydrofuro[3,2-c]pyridine hydrochloride, 0.33 g (1.7 mmol) of 6-phenylhexanoic acid and 0.87 ml (6.3 mmol) of triethylamine in 30 ml of dichloromethane, 0.36 ml (2.4 mmol) of diethyl cyanophosphonate was added dropwise under ice-cooling, followed by overnight stirring at room temperature. The reaction mixture was poured into aqueous sodium hydroxide and extracted with dichloromethane 3 times. The combined organic layer was dried over anhydrous magnesium sulfate; the solvent was distilled off under reduced pressure. The resulting crude product was purified by silica gel chromatography (hexane/ethyl acetate=6/1 to 3/1) to yield the desired product.
