Triethylamine → HCID 19600110, compound

Participants

Reaction Steps

To a solution of 0.114 g (0.720 mmol) of 4,5,6,7-tetrahydrofuro[2,3-c]pyridine hydrochloride, 0.188 g (0.7 mmol) of 4-(3-chlorobenzoyl)benzoic acid and 0.40 ml (2.9 mmol) of triethylamine in 30 ml of dichloromethane, 0.18 g (1.1 mmol) of diethyl cyanophosphonate was added dropwise under ice-cooling, followed by overnight stirring at room temperature. This mixture was poured into water and extracted with dichloromethane 2 times. The combined organic layer was washed with water and 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/dichloromethane=4/1/1). The resulting purified product was washed with hexane to yield the desired product.
