反応手順
To a stirred mixture of 2-aminoethyl isopropyl ether (25 mg, 242 μmol) and 3-{[6-cyclopropyl-3-(pyrimidin-5-ylamino)-pyrazine-2-carbonyl]-amino}-isonicotinic acid (101 mg, 267 μmol) at rt in THF (5 ml) under an argon atmosphere were added 4-methylmorpholine (123 mg, 134 μl, 1.21 mmol) and HATU (184 mg, 485 μmol). The mixture was heated to reflux and stirring was continued for 1 day. The reaction mixture was concentrated. The crude product was purified by silica gel chromatography using an EtOAc/MeOH gradient as eluent. After trituration with MeOH, the title compound (90 mg, 80%) was obtained as yellow solid.
