Reaction Steps

TMSI (100 μL, 0.734 mmol) was added to a solution of 2′-methoxy-N-(4-(trifluoromethoxy)phenyl)-[3,3′-bipyridine]-5-carboxamide (Example 62, 79 mg, 0.203 mmol) in CHCl3 (4 mL) and the RM was stirred at 60° C. overnight. The RM was cooled to RT, poured into MeOH and the solvent was evaporated off under reduced pressure. The residue was treated with aq. 5% NH3 and extracted with EtOAc. The combined extracts were washed with brine, dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give the product which was recrystallized from hot EtOAc to afford the title compound as beige crystals. UPLC-MS (Condition 2) tR0.87 min, m/z=376.1 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 6.38 (t, J=6.65 Hz, 1H) 7.40 (d, J=8.99 Hz, 2H) 7.51 (d, J=6.26 Hz, 1H) 7.86-7.96 (m, 3H) 8.61-8.66 (m, 1H) 9.00-9.04 (m, 1H) 9.09-9.13 (m, 1H) 10.63 (s, 1H) 12.03 (br. s, 1H).
