실험 절차

Dess-Martin periodinane (110 mg, 0.260 mmol) was added to a stirred, cooled (room temperature) mixture of cyclopropyl[5-(3-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]methanol (Example 4A-5, 85 mg, 0.217 mmol) in dichloromethane (0.72 mL) and the mixture was stirred at room temperature for 30 min. The mixture was cooled, diluted with ethyl acetate, washed with aqueous sodium sulfite then brine, dried (MgSO4), filtered, and concentrated. The residue was purified by flash chromatography to give cyclopropyl[5-(3-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]methanone (43 mg, 0.110 mmol, 50.8%) as a colorless solid. APCI: [M+H]+ m/z 391.0. 1H NMR (400 MHz, CDCl3): δ 8.71 (d, J=4.90, 1H), 8.26 (s, 1H), 8.24 (s, 1H), 7.58-7.50 (m, 2H), 7.46 (t, J=7.87, 1H), 7.42-7.38 (m, 1H), 7.13 (d, J=4.91, 1H), 3.28-3.23 (m, 1H), 1.39-1.34 (m, 2H), 1.22-1.17 (m, 2H). rhSYK activity=+++
