Procedure
2-((1-(3-bromobenzyl)-4,6-difluoro-1H-indol-3-yl)sulfonyl)acetic acid (30 mg, 0.68 mmol) from Step D, 2-amino-pyridine (13 mg, 0.135 mmol), PyClu (45 mg, 0.135 mmol), and DIEA (29 μL, 0.169 mmol) were added to dichloroethane (3 mL) and microwave irradiated at 110° C. for 30 minutes. The solvent was removed in vacuo and the remaining residue was purified on a Gilson reverse phase HPLC system with a Phenomenex, Luna 50×21.2 mm, 5 uM C18 column (5%-95% water:acetonitrile over 6 min) to yield the desired product. LCMS>99% 215 nm, RT=0.78 min, m/z=520 ([79Br]m+1), 522 ([81Br]m+1). 1H NMR (400 MHz, DMSOD6) 10.89 (s, 1H), 8.47 (s, 1H), 8.41 (d, J=4.0 Hz, 1H), 8.02 (d, J=8.0 Hz, 1H), 7.86 (t, J=8.4 Hz, 1H), 7.66 (s, 1H) 7.59 (d, J=8.4 Hz, 2H), 7.38-7.34 (m, 2H), 5.61 (s, 2H), 4.64 (s, 2H), 2.16 (s, 3H). HRMS found 520.0142; calculated for C22H17N3O3SBrF2, 520.0142.
