Procedure
535 mg of 1-(2,6-dichloropyridin-4-yl)ethanone (Steps 1 and 2 of Example 29), 391 mg of (S)-(−)-1-(4-fluorophenyl)ethylamine, 262 mg of (±)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl, 1.28 g of cesium carbonate and 63 mg of palladium acetate were added in turn to 10 ml of degassed toluene, and the mixture was stirred at 100° C. for 3 hours under argon atmosphere. The reaction solution was purified by silica gel column chromatography to obtain 132 mg of the objective compound as pale yellow powder.
