Acetic Acid → HCID 51263596, compound

Participants

Reaction Steps

To a solution of 1-(4-nitrophenyl)-piperazine (0.6 g, 2.89 mmol) in THF (10 mL) was added fufaraldehyde (0.41 g, 4.31 mmol), acetic acid (3 mL) and water (1.5 mL) and the mixture stirred at r.t. for half an hour. Sodium cyanoborohydride (0.27 g, 4.31 mmol) was added and the reaction heated at reflux for four hours. The reaction was cooled and the solvent evaporated. The resulting residue was diluted with water and extracted with dichloromethane. The combined organic layers were washed with saturated sodium bicarbonate and brine solution, dried over sodium sulfate, filtered and concentrated. Purification by column chromatography over silica gel (60-120 mesh) using 5% methanol/chloroform as eluent afforded 1-furan-2-ylmethyl-4-(4-nitrophenyl)-piperazine (0.45 g, 54%) as a yellow solid.
