Reaction Steps

General Procedure C. To a solution of ethyl3-formyl-2-isopropyl-1H-indole-6-carboxylate (Compound 34, 2.08 g, 8.04 mmol) in DMF (15 ml) was added K2CO3 (3.32 g, 24.1 mmol) and benzyl bromide (1.91 ml, 16.1 mmol). The reaction was stirred at room temperature for 12 h, diluted with EtOAc, washed with H2O, brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by chromatography on silica gel (0→35% EtOAc-hexanes) to yield the title compound as a yellow oil.
