Versuchsvorschrift

To flask containing (4-chloro-2-methoxy-3-(4-(trifluoromethyl)benzyl)quinolin-6-yl)(1-methyl-1H-1,2,3-triazol-5-yl)methanone (250 mg, 0.54 mmol, Intermediate 9: step b) was added THF (15 mL). The solution was cooled to −78° C. and MeLi (1.6 M in Et2O, 0.4 mL, 0.64 mmol) was introduced. The reaction mixture was quenched after 25 minutes with aqueous NH4Cl solution and the aqueous portion was extracted with EtOAc (4×30 mL). The combined organics were washed with brine, dried over MgSO4, filtered and concentrated to dryness to afford an off white solid. Chromatography on silica gel (10% CH3CN-DCM increasing to 30% CH3CN) provided the title compound as a white amorphous solid. 1H NMR (500 MHz, CDCl3) δ 8.21 (d, J=2.1 Hz, 1H), 7.80 (d, J=8.7 Hz, 1H), 7.74 (d, J=2.9 Hz, 1H), 7.50 (d, J=8.2 Hz, 2H), 7.45-7.35 (m, 3H), 4.35 (s, 2H), 4.07 (s, 3H), 3.71 (s, 3H), 2.82 (br. s, 1H), 2.06 (s, 3H); MS (ESI): mass calcd. for C23H20ClF3N4O2, 476.1, m/z found 477.1 [M+H]+. 1-(4-Chloro-2-methoxy-3-(4-(trifluoromethyl)benzyl)quinolin-6-yl)-1-(1-methyl-1H-1,2,3-triazol-5-yl)ethanol was purified by chiral SFC (Stationary phase: Lux 5 m cellulose-3, 4.6 mm×250 mm, Mobile phase: 12% EtOH, 0.2% Et3N, 88% CO2) to give 2 enantiomers. The first eluting enantiomer was Example 11b and the second eluting enantiomer was Example 11c.
