Procedure

A mixture of 405.9 mg of 2,4-dichloro-6-methylpyrimidine, 585.5 mg of 1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazol-3-amine (WO2006/046734, page 132, Reference 2), 231.9 mg of 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene, 208.6 mg of tris(dibenzylideneacetone)dipalladium(0)-chloroform complex, 751.2 mg of potassium phosphate and 20 ml of 1,4-dioxane was stirred at 80° C. overnight, followed by cooling to room temperature. The reaction mixture was diluted with ethyl acetate. An insoluble matter was filtered off using Celite, and washed with ethyl acetate. The filtrate was washed with saturated aqueous sodium bicarbonate solution and brine, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated in vacuo. The resulting residue was purified by a silica gel column chromatography (eluent: hexane/ethyl acetate=10/1−2/3) to give the title compound.
