Reaction Steps

30 mmol of 2,5-diphenyl-3-chlorofuran (7.64 g), 32 mmol of freshly distilled piperidine (3.0 g), 32 mmol of KOtBu (3.6 g), 2 mmol of lithium chloride (42.5 mg) and 44 mg of trans-di-μ-acetatobis[2-[bis(1,1-dimethylethyl)phosphino]-2-methylpropyl-C,P]dipalladium(II) (0.2 mol %) are suspended in 50 ml of THF and placed in a pressure tube under protective gas. After 12 hours at 110° C., the tube is cooled to room temperature, the salts are filtered off and washed with petroleum ether. The solvents are removed from the filtrate on a rotary evaporator. Crystallization from 96% strength ethanol gives 2,5-diphenyl-3-piperidinofuran as a colorless solid; yield: 84%; melting point: 103° C.
