General Procedure W. A mixture of 1-benzyl-3-(3,4-difluorobenzylcarbamoyl)-2-isopropyl-1H-indol-6-yl trifluoromethanesulfonate (Compound 160, 50 mg, 0.088 mmol), pyridin-4-ylboronic acid (22 mg, 0.18 mmol), Pd(PPh3)4 (5.0 mg, 0.0043 mmol), K2CO3 (61 mg, 0.44 mmol), and LiCl (19 mg, 0.44 mmol) in toluene (3 ml), MeOH (1 ml), and H2O (0.5 ml) was heated at 90° C. for 16 h. The reaction was then cooled to room temperature, diluted with EtOAc, washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by chromatography on silica gel (0→100% EtOAc-hexanes) to yield the title compound.
