To a cooled (0° C.) solution of 3,3,3-trifluoro-2-(4-methoxybenzylamino)-2-methyl propanenitrile (1.5 g, 5.81 mmol) in dry diether ether (50 ml) was added LiAlH4 (11.62 ml of a 2M solution in THF) and the resulting mixture was stirred at RT overnight. The reaction mixture was hydrolyzed by successive addition of water 15% KOH, and water. The resulting precipitate was filtered on Celite® (filter material) and the organic portion was washed with water, dried over MgSO4 and concentrated under reduced pressure to afford the title product; 1H NMR (400 MHz, Methanol-d4) δ 7.97 (1H, s), 7.85 (1H, s), 7.60 (1H, s), 3.97 (3H, s), 3.77 (1H, m), 3.56 (1H, m), 1.37 (3H, s)
