Procedure

Under argon atmosphere, 92 mg of (S)-1-{2-[1-(4-fluorophenyl)ethylamino]-6-(pyrazin-2-ylamino) pyrimidin-4-yl}piperidine-4-carboxylic acid (Example 85) was dissolved in 2 ml of tetrahydrofuran, and 41 mg of N,N′-carbonyldiimidazole was added thereto, and the mixture was stirred at 70° C. for 1 hour. The reaction solution was air-cooled to room temperature, and 80 mg of methanesulfonamide and 63 μl of 1,8-diazabicyclo[5,4,0]-7-undecene were added thereto, and the mixture was stirred at room temperature for 4 hours. The reaction solution was diluted with water, and the pH of the mixture was adjusted to 4 by using acetic acid. The reaction solution was subjected to extraction with ethyl acetate, and the organic layer was washed in turn with water and brine, and then dried over magnesium sulfate. The solvent was distilled off under reduced pressure to obtain 42 mg of the objective compound as white powder.
