Sodium Hydroxide → 5-Benzyl-4,5,6,7-tetrahydro-furo[3,2-c]pyridine

Participants

Reaction Steps

To a solution of 0.209 g (0.837 mmol) of N-benzyl-N-(3-furylmethyl)-2-chloroethylamine in 50 ml of tetrahydrofuran, 1.05 ml (1.67 mmol) of 1.6 M n-butyl lithium in hexane was added under ice-cooling, followed by stirring at room temperature for 2 hours. 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 column chromatography (hexane/ethyl acetate=9/1) to yield 5-benzyl-4,5,6,7-tetrahydrofuro[3,2-c]pyridine.
