Participants

Reaction Steps

To a solution of 1.173 g (7.349 mmol) of 4,5,6,7-tetrahydrofuro[2,3-c]pyridine hydrochloride, 1.90 g (7.35 mmol) of (Z)-4-chloro-4'-stilbenecarboxylic acid and 4.10 ml (29.4 mmol) of triethylamine in 30 ml of N,N-dimethylformamide, 1.34 ml (8.82 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.
