Reaction Steps

To a solution of 3-fluoro-4-(trifluoromethyl)benzonitrile (300 mg, 1.59 mmol) in DMSO (5.0 mL) was added piperidine (675 mg, 7.93 mmol), and the mixture was stirred for 43 hours at 55° C. After the mixture was cooled to room temperature, ethylacetate was added and washed with water then brine. The organic layer was dried over MgSO4, filtered, and concentrated under reduced pressure. The obtained residue was purified by column chromatography on silica gel (hexane:ethylacetate=10:1) to afford 3-piperidin-1-yl-4-(trifluoromethyl)benzonitrile (353 mg, 88% yield).
