実験手順

286 mg of (S)-4,6-dichloro-N-[1-(4-fluorophenyl)ethyl]pyrimidine-2-amine (Reference Example 1), 411 mg of 5-(tributylstannyl)thiazole and 115 mg of tetrakis(triphenylphosphine)palladium were added in turn to degassed dimethylformamide, and then the mixture was stirred at 100° 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 175 mg of (S)-4-chloro-N-[1-(4-fluorophenyl)ethyl]-6-(thiazol-5-yl)pyrimidine-2-amine as a white solid.
