Reaction Steps

225 mg of 2,6-dichloro-4-[1-(methylsulfonyl)-1,2,3,6-tetrahydropyridin-4-yl]pyridine, 104 μl of (S)-(−)-1-(4-fluorophenyl)ethylamine, 68 mg of (±)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl, 359 mg of cesium carbonate and 17 mg of palladium acetate were added in turn to 5 ml of degassed tetrahydrofuran, and the mixture was stirred at 60° C. for 10 hours under argon atmosphere. The reaction solution was diluted with ethyl acetate, and filtrated to remove precipitates, and then the filtrate was concentrated under reduced pressure, and the obtained residue was purified by silica gel column chromatography to obtain 118 mg of the objective compound as pale yellow powder.
