Procedure

To a solution of 3-(3,4-difluorobenzylcarbamoyl)-2-isopropyl-1-(pyridin-2-ylmethyl)-1H-indol-6-yl trifluoromethanesulfonate (Compound 202, 100 mg, 0.18 mmol) in toluene (10 ml) at 25° C., bubbled with argon then added morpholine (22 mg, 0.25 mmol), LiN(TMS)2 (1M in THF, 0.37 ml, 0.40 mmol), Pd2 (dba)3 (3.2 mg, 0.0035 mmol), and X-Phos (4 mg, 0.011 mmol). The reaction was stirred for 12 h at 110° C., diluted with EtOAc, the organic layer was 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 as a light brown solid.
