Reaction Steps

(5,8-Difluoroquinazolin-4-yl)-{2-[4-(4-trifluoromethyl-pyridin-2-yloxy)-3-vinylphenyl]-ethyl}-amine (250 mg), 10% Pd—C (100 mg) and ethyl acetate (10 mL) were added to a 230 mL Corning shaker bottle filled with nitrogen gas. The bottle was evacuated, then charged with hydrogen (55 psi starting pressure) and shaken overnight. The reaction mixture was filtered through Celite, and concentrated in vacuo. The residue was purified by reverse phase chromatography (C-18 solid phase with acetonitrile/water eluent, 0.5% H3PO4) to provide (5,8-difluoroquinazolin-4-yl)-{2-[3-ethyl-4-(4-trifluoromethylpyridin-2-yloxy)-phenyl]-ethyl}-amine as a white powder (77 mg), M.P. 121-122°. 1H NMR (CDCl3): δ 8.69 (s, 1H), 8.31 (d, 1H), 7.36 (m, 1H), 7.22 (m, 1H), 7.17 (m, 2H), 7.13 (s, 1H), 7.00 (m, 2H), 6.76 (bm, 1H), 3.95 (m, 2H), 3.04 (t, 2H), 2.55 (q, 2H), 1.16 (t, 3H). MS: m/z 474.
