Procedure

To a suspension of 1-methyl-7-(pyridine-4-yloxy)-1H-indole-2-carboxylic acid (40 mg, 0.15 mmol) in DMF (1 mL) was added Hunig's base (52 microL, 0.3 mmol) resulting in a clear solution. After 5 min, HATU (90 mg, 0.23 mmol) and HOAT (3 mg, 0.02 mmol) were added followed by the above anisidine (37 mg, 0.15 mmol). The mixture was stirred overnight. The reaction mixture was diluted with EtOAc (30 mL), washed with water, brine, dried over anhydrous Na2SO4 and concentrated in vacuo. The crude product was purified by column chromatography (eluting with 30-80% EtOAc in hexane) to give the title compound (50 mg, 75%).
