Reaction Steps

3-Iodo-N-(4-(trifluoromethoxy)phenyl)benzamide (Stage 1.1, 204 mg, 0.5 mmol), 1H-imidazole (68.1 mg, 1 mmol), CuI (9.52 mg, 0.050 mmol), L-proline (11.51 mg, 0.100 mmol), K2CO3 (138 mg, 1.000 mmol) and DMSO (500 μL) were added to a vial, which was sealed, evacuated/purged with argon and the RM stirred at 90° C. for 70 h. The RM was diluted with DCM/EtOAc, filtered and stirred with of Chelex® 100 (950 mg). The mixture was washed with sat. aq. Na2CO3, brine, dried over MgSO4 and the solvent was evaporated off under reduced pressure to give the crude product which was purified by flash chromatography (Silica gel column, 12 g, DCM/MeOH+1% NH4OH from 2% B to 10% MeOH+1% NH4OH) to afford the title compound as an off white powder. UPLC-MS (Condition 1) tR=1.55 min, m/z=348 [M+H]+, m/z=346.1 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 7.16 (s, 1H) 7.40 (d, J=8.8 Hz, 2H) 7.69 (t, J=7.9 Hz, 1H) 7.85-7.93 (m, 2H) 7.90 (d, J=9.0 Hz, 3H) 8.18 (s, 1H) 8.37 (s, 1H) 10.52 (s, 1H).
