실험 절차

To 155 mg of (S)-4-chloro-N-[1-(4-fluorophenyl)ethyl]-6-(thiazol-5-yl)pyrimidine-2-amine, 53 mg of 2-aminopyrazine, 72 mg of 4,5-bis(diphenylphosphino)-9,9′-dimethylxanthene, 196 mg of tripotassium phosphate and 81 mg of tris(dibenzylideneacetone)(chloroform)dipalladium, was added 4 ml of 1,4-dioxane, and the mixture was subjected to degassing, and substituted by argon gas, and then was stirred at 100° C. for 5 hours. 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 105 mg of the objective compound as pale yellow powder.
