実験手順
(R)-2-(4-Amino-3-(5-cyclopropyl-1H-pyrazol-3-ylamino)-2,6-difluorophenylamino)-2-(4-fluorophenyl)ethanol (Method 104, 0.230 g, 0.57 mmol) and formamidine acetate (0.119 g, 1.14 mmol) in EtOH (10 ml) was heated at reflux for 1 hour. Saturated sodium bicarbonate solution (5 ml) and EtOAc (15 ml) were added. The organic layer was separated, washed with brine (3 ml) and dried over sodium sulfate. The solvent was removed under reduced pressure and the residue was purified by chromatography (Hex-EtOAc=1:1) to give the title compound as off white solid (0.070 g, 30%). 1H NMR (400 MHz) 12.83 (s, 1H), 8.20 (s, 1H), 7.34 (m, 3H), 7.07 (t, J=8.8 Hz, 2H), 6.14 (s, 1H), 5.14 (d, J=9.6 Hz, 1H), 4.97 (t, J=5.6 Hz, 1H), 4.62 (m, 1H), 3.64-3.74 (m, 2H), 1.97 (m, 1H), 1.00 (m, 2H), 0.76 (m, 2H). MS: Calcd.: 413; Found: [M+H]+ 414.
