Procedure
3-Iodo-4-methyl-N-(4-(trifluoromethoxy)phenyl)benzamide (Stage 13.1, 100 mg, 0.237 mmol), thiazole (60 mg, 0.712 mmol), KOAc (69.9 mg, 0.712 mmol) and Pd(OAc)2 (0.267 mg, 1.187 μmol) were added to a vial, which was sealed, evacuated/purged with argon. DMA (720 μL) was added and the RM was stirred at 130° C. for 2.5 days. The RM was diluted with THF (3 mL), stirred overnight with Si-Thiol (1.44 mmol/g, 16.49 mg, 0.024 mmol) and filtered. The filtrate was treated with 2 M HCl (40 mL) and extracted with TBME. The combined extracts were washed with 1 M HCl, sat. NaHCO3, brine, dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give a residue which was purified by preparative SFC (Column NH2, from 10% to 15% in 2.4 min) to afford the title compound as a colorless solid. UPLC-MS (Condition 2) tR=1.18 min, m/z=379.2 [M+H]+, m/z=377.2 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 2.44 (s, 3H) 7.37 (d, J=8.31 Hz, 2H) 7.54 (d, J=8.07 Hz, 1H) 7.86-7.91 (m, 2H) 7.93 (dd, J=7.82, 1.96 Hz, 1H) 8.02 (d, J=1.96 Hz, 1H) 8.10 (d, J=0.73 Hz, 1H) 9.23 (d, J=0.73 Hz, 1H) 10.43 (s, 1H).
