Following General Procedure E, 1-benzyl-6-(ethoxylcarbonyl)-2-isopropyl-1H-indole-3-carboxylic acid (Compound 39, 93 mg, 0.254 mmol) in CH2Cl2 (6 ml) was added EDC (97 mg, 0.508 mmol) and DMAP (46 mg, 0.381mmol), followed by (5-fluoropyridin-3-yl)methanamine (81 mg, 0.63 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→80% EtOAc-hexanes) to yield the title compound as a yellow solid.
