Reaction Steps

To a solution of N-(3,4-difluorobenzyl)-2-formyl-6-isopropoxy-1-(pyridin-2-ylmethyl)-1H-indole-3-carboxamide (Compound 105, 102 mg, 0.23 mmol) in 1,2-dimethoxy-ethane (15 ml) was added MeMgBr (1.4 M in toluene-THF, 0.5 ml, 0.70 mmol) at 0° C. The reaction was stirred at room temperature for 2 h and more MeMgBr (1.0 ml, 1.4 mmol) was added. The reaction was stirred at room temperature for another 2 h and was quenched with ice, extracted 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.
