To a flask containing (4-chloro-2-methoxy-3-(4-(trifluoromethyl)benzyl)quinolin-6-yl)(1-methyl-1H-imidazol-5-yl)methanone (400 mg, 0.87 mmol, Intermediate 12: step b) was added THF (20 mL) and the solution was cooled to −43° C. (CH3CN—CO2). MeLi (1.6 M in Et2O, 0.63 mL, 1.01 mmol) was then introduced. After 30 minutes, the reaction mixture was quenched with saturated aqueous NH4Cl solution. The aqueous portion was extracted with EtOAc (4×30 mL) and the combined organics were washed with brine, dried over MgSO4, filtered and concentrated to dryness. Chromatography on silica gel (30% CH3CN-DCM increasing to 3% MeOH-DCM) provided the title compound as a white amorphous solid. 1H NMR (400 MHz, CDCl3) δ 8.24 (d, J=1.9 Hz, 1H), 7.77 (d, J=8.9 Hz, 1H), 7.49 (dd, J=8.6, 2.2 Hz, 3H), 7.40 (d, J=8.1 Hz, 2H), 7.34 (s, 1H), 7.17 (d, J=0.8 Hz, 1H), 4.35 (s, 2H), 4.07 (s, 3H), 3.25 (s, 3H), 3.0 (br. s, 1H), 1.99 (s, 3H); MS (ESI): mass calcd. for C24H21ClF3N3O2, 475.1, m/z found 475.9 [M+H]+. 1-(4-Chloro-2-methoxy-3-(4-(trifluoromethyl)benzyl)quinolin-6-yl)-1-(1-methyl-1H-imidazol-5-yl)ethanol was purified by chiral SFC: (Stationary phase: CHIRALCEL OD-H, 5 μm, 250×20 mm), Mobile phase: 70% CO2, 30% MeOH), to give 2 enantiomers. The first eluting enantiomer was Example 9b and the second eluting enantiomer was Example 9c.
