Procedure

{2-[4-(3,5-dichloro-2-trifluoromethylpyridin-4-yloxy)-phenyl]-ethyl}-(5,8-difluoroquinazolin-4-yl)-amine (700 mg, 1.4 mol) was dissolved in 2B EtOH (100 mL) under nitrogen in a Parr shaker bottle. Triethylamine (130 mg) and 10% Pd/C (200 mg) were added and the bottle was charged with H2 to an initial pressure of 50 psi. After shaking for approx. 10 min (approx 1 psi H2 uptake), the reaction was filtered through Celite and concentrated in vacuo to provide a white solid. The solid was partitioned between water and EtOAc twice, and the pooled fractions were dried and concentrated in vacuo. The residue was triturated with Et2O, to afford 310 mg of {2-[4-(3-chloro-2-trifluoromethylpyridin-4-yloxy)-phenyl]-ethyl}-(5,8-difluoroquinazolin-4-yl)-amine as a white crystalline solid, M.P. 129-131°. 1H NMR (400 MHz, CDCl3) δ 8.69 (s, 1 H), 8.35 (d, J=5.4 Hz, 1 H), 7.40-7.31 (m, 3 H), 7.12-7.06 (m, 2 H), 7.05-6.97 (m, 1 H), 6.85-6.66 (m, 2 H), 4.01-3.92 (m, 2 H), 3.09 (t, J=7.1 Hz, 2 H); MS: m/z 480.
