Participants

Reaction Steps

70 mg of (S)-2-[1-(4-fluorophenyl)ethylamino]-6-(pyrazin-2-ylamino) isonicotinic acid (Example 141) was dissolved in 0.5 ml of dimethylformamide, 81 mg of dimethylamine hydrochloride, 37 mg of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, 32 mg of 1-hydroxy-7-azabenzotriazole, and 0.18 ml of diisopropylethylamine were added thereto, and the mixture was stirred at room temperature for 4 hours. The reaction solution was diluted 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, and then the obtained residue was purified by silica gel column chromatography to obtain 45 mg of the objective compound as pale yellow powder.
