실험 절차

To a solution of 1.209 g (7.575 mmol) of 4,5,6,7-tetrahydrofuro[2,3-c]pyridine hydrochloride, 1.80 g (7.58 mmol) of 4-(1-phenylcyclopropyl)benzoic acid and 4.22 ml (30.3 mmol) of triethylamine in 50 ml of N,N-dimethylformamide, 1.38 ml (9.09 mmol) of diethyl cyanophosphonate was added dropwise, followed by overnight stirring at room temperature. This mixture was poured into water and extracted with diethyl ether 3 times. The combined organic layer was dried over anhydrous sodium sulfate; the solvent was distilled off under reduced pressure. The resulting crude product was purified by silica gel column chromatography (hexane/ethyl acetate=6/1 to 3/1) to yield the desired product.
