To a flask containing tert-butyl 3-((4-chloro-2-methoxy-3-(4-(trifluoromethyl)benzyl)quinolin-6-yl)(hydroxy)(1-methyl-1H-1,2,3-triazol-5-yl)methyl)azetidine-1-carboxylate (165 mg, 0.27 mmol, Example 123) was added formic acid (5 mL) at room temperature followed by 6 N aqueous HCl (0.21 mL). The mixture was stirred at room temperature for 40 minutes and then MeOH (5 mL) was added and the mixture was stirred for 20 minutes before concentrating. The resulting oil was chromatographed directly on silica gel (10% 2 M NH3-MeOH-DCM increasing to 12% 2 M NH3-MeOH) to provide the title compound as an off white powder. 1H NMR (500 MHz, CDCl3) δ 8.30 (d, J=2.1 Hz, 1H), 8.20 (s, 1H), 7.92 (s, 1H), 7.76 (d, J=8.8 Hz, 1H), 7.47 (d, J=8.1 Hz, 2H), 7.42-7.32 (m, 3H), 4.52-4.34 (m, 2H), 4.33-4.16 (m, 3H), 4.05 (s, 3H), 3.96-3.80 (m, 1H), 3.71 (s, 4H); MS (ESI): mass calcd. Chemical Formula: C25H23ClF3N5O2; Exact Mass: 517.2. m/z found 517.9 [M+H]+.
