Water → 5-(4-Phenylbenzoyl)-4,5,6,7-tetrahydrofuro[3,2-c]pyridine

Participants

Reaction Steps

To a solution of 0.160 g (1.000 mmol) of 4,5,6,7-tetrahydrofuro[3,2-c]pyridine hydrochloride and 0.55 ml (4.0 mmol) of triethylamine in 30 ml of dichloromethane, 0.26 g (1.2 mmol) of 4-biphenylcarbonyl chloride was added under ice-cooling, followed by overnight stirring at room temperature. This solution 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=4/1) to yield the desired product.
