Versuchsvorschrift

100 mg of (S)-6-chloro-N2-[1-(4-fluorophenyl)ethyl]-N4-(pyrazin-2-yl)pyrimidine-2,4-diamine, 145 mg of 4-(methylsulfonyl)phenylboronic acid, 123 mg of sodium carbonate and 17 mg of tetrakis(triphenylphosphine)palladium were added in turn to a degassed mixed solvent of 3 ml of 1,4-dioxane and 1.2 ml of water, and the mixture was stirred at 100° C. for 3 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 124 mg of (S)—N2-[1-(4-fluorophenyl)ethyl]-6-[4-(methylsulfonyl)phenyl]-N4-(pyrazin-2-yl)pyrimidine-2,4-diamine as white powder. The obtained compound was dissolved in methanol, and an equivalent of 1N hydrochloric acid was added thereto, and then the solvent was removed to obtain the objective compound as white powder.
