Procedure
8.3 g of methyl 2,6-dichloroisonicotinate, 6.1 ml of (S)-(−)-1-(4-fluorophenyl)ethylamine, 20.5 g of cesium carbonate, 2.1 g of (±)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl and 505 mg of palladium acetate were added in turn to 100 ml of degassed 1,4-dioxane, and the mixture was stirred at 70° C. for 7 hours under argon atmosphere. The reaction mixture was purified by silica gel column chromatography to obtain 4.4 g of the objective compound as pale yellow powder.
