Procedure
To solution of 1-(tert-butoxycarbonyl)-3-iodo-1H-indole-5-carboxylic acid (1 g, 2.57 mmol) in DMF (10 mL) at 0° C. was added EDC.HCl (741 mg, 3.86 mmol) and HOBT-NH3 complex (825 mg, 5.15 mmol). The reaction mixture was stirred at RT for 3 h and then extracted with DCM (15 mL). The organic layer was washed with brine, dried over Na2SO4, filtered, and concentrated to dryness. The crude product was purified by column chromatography to obtain title compound as an off white solid (550 mg, 50%). MS (ESI, Neg. ion) m/z: 286.9 (M+1).
