Procedure

NaH (60% dispersion in mineral oil, 4.52 mmol, 186 mg) was added portion-wise to a solution of methyl 3-phenyl-1H-indole-6-carboxylate TFA salt 62c (2.07 mmol, 757 mg) in DMF at 0° C. and the mixture was stirred for 20 min. Methyl iodide (2.28 mmol, 0.14 mL) was added and the reaction mixture was maintained at 0° C. for 1 h. Water was then added and the reaction was extracted with EtOAc. The organics were concentrated and purified by flash column chromatography (silica gel, 15% EtOAc/hexanes) to give 62d.
