N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-9-(4-fluorophenyl)-7-methylene-6,7,8,9-tetrahydro-5H-[1,2,4]triazolo[1,5-a]azepin-2-amine (65 mg, 0.140 mmol, from example 133) was dissolved in ethanol (5 mL), flushed with nitrogen, and chilled to 0° C. Platinum on sulfided carbon (136 mg, 0.140 mmol) was added and the flask was repeated evacuated and flushed with hydrogen gas (balloon). The reaction mixture was stirred under an atmosphere of hydrogen gas at rt for 16 h. The reaction mixture was purged with nitrogen, filtered over celite. The celite was washed with methanol and the combined filtrates were concentrated in vacuo. The crude product was purified using reverse phase preparatory HPLC (AcCN/water/ammonium acetate) to afford the titled compound as a mixture of diasteromers (51.6 mg, 74% yield). LC-MS (M+H)+ 467.2. 1H NMR (500 MHz, CHLOROFORM-d, mixture of diastereomers) δ ppm 7.53 (1 H, dd, J=16.2, 1.5 Hz), 7.41 (1 H, t, J=2.1 Hz), 7.29-7.34 (1 H, m), 6.95-7.16 (5 H, m), 6.71-6.79 (1 H, m), 4.62 (1 H, br. s.), 3.96-4.16 (1 H, m), 3.73-3.88 (3 H, m), 2.00-2.10 (2 H, m), 1.91 (1 H, dd, J=14.2, 6.6 Hz), 1.71-1.85 (1 H, m), 1.50-1.68 (2 H, m), 1.09 (3 H, dd, J=16.9, 6.6 Hz).
