Procedure

50 mg of ethyl (S)-1-{6-chloro-2-[1-(4-fluorophenyl)ethylamino]pyrimidin-4-yl}-1H-pyrazole-4-carboxylate, 15 mg of 2-aminopyrazine, 12 mg of 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl, 17 mg of sodium t-butoxide and 7 mg of tris(dibenzylideneacetone)(chloroform)dipalladium were added in turn to 10 ml of degassed toluene, and the mixture was stirred at 100° C. for 2 hours under argon atmosphere. The reaction solution was purified by silica gel column chromatography to obtain 45 mg of the objective compound as white powder.
