379 mg of 2,6-dichloro-4-(1-methyl-1H-pyrazol-4-yl)pyridine, 300 mg of 4-(4-fluorophenyl)oxazolidin-2-one, 192 mg of 4,5-bis(diphenylphosphino)-9,9′-dimethylxanthene, 705 mg of tripotassium phosphate and 172 mg of tris(dibenzylideneacetone)(chloroform)dipalladium were added in turn to 10 ml of degassed 1,4-dioxane, and the mixture was stirred at 90° C. for 5 hours under argon atmosphere. The reaction solution was diluted with ethyl acetate. The solution was washed in turn with water and brine and then dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and then the obtained residue was purified by silica gel column chromatography to obtain 212 mg of the objective compound as yellow powder.
