Reaction Steps

A solution of 410 mg (1.95 mmol) N-(p-tolyl)-o-aminobenzaldehyde 326 mg (2.15 mmol), (2-furoyl)acetone and 50 mg piperidine in 4 ml 95% ethanol was heated overnight under reflux. Removal of he volatile materials left a black, gummy oil which was taken up in dichloromethane and, after being washed with 3M NaOH, brine, and dried (MgSO4), purified by flash chromatography [eluent, 3:2 pentane-diethyl ether (3:2)] yielding 355 mg (1.50 mmol, 77%) product.
