Reaction Steps

To a solution of N-{4-[(1R)-1-(1H-pyrazol-5-yl)ethyl]phenyl}-4-(trifluoromethyl)-1,3-thiazol-2-amine (0.421 g, 1.24 mmol) in EtOAc (5 mL) m-CPBA (256 mg, 1.5 mmol) was added and the resulting mixture was stirred at room temperature overnight. The crude was diluted with EtOAc (10 ml), washed with water (2×10 ml) and dried over anhydrous Na2SO4. After solvent evaporation, the crude was purified by flash chromatography to give the pure 5-[(1R)-1-(4-{[4-(trifluoromethyl)-1,3-thiazol-2-yl]amino}phenyl)ethyl]-1H-pyrazol-1-ol (7) (0.295 g, 0.65 mmol) as a white solid (67%). [α]D=−28 (c=0.82; CH3OH); 1H-NMR (CD3OD): δ 9.40 (bs, 1H, NH); 7.55 (d, 1H, J=2.5 Hz); 7.40 (d, 2H, J=7 Hz); 7.35 (d, 2H, J=7 Hz); 7.15 (s, 1H), 6.25 (d, 1H, J=2.4 Hz); 3.80 (q, 1H, J=7 Hz); 1.60 (d, 3H, J=7 Hz).
