Add a solution of 1M lithium aluminum hydride in THF (12 mL, 12 mmol) dropwise to an ice-cooled solution of (R)-4-[2-(1-methyl-2,2,2-trifluoroethylamino)-thiazol-4-yl]-benzonitrile in anhydrous THF (10 mL). Heat to reflux for 1 h, cool to room temperature, quench by slow addition of water (12 mL), ether (50 mL), 1N NaOH (12 mL) and additional water (36 mL). Add EtOAc (50 mL), stir vigorously for 20 min and filter over a bed of Celite®. Dry the organic phase over MgSO4, filter and concentrate in vacuo to obtain the title compound (765 mg, 64%). MS (ES+) m/z: 302 (M+H)+.
