Procedure

To a solution of methyl (7-nitro-1H-indol-3-yl)acetate from Step B (545 mg, 2.71 mmol) was added cesium carbonate (927 mg, 2.85 mmol) and methyl bromoacetate (0.26 mL, 2.84 mmol) in DMF (10 mL). The reaction mixture was stirred at ambient temperature for 18 h, then quenched with H2O (50 mL). The solid precipitate was collected by filtration to give the title compound. MS: m/z=308 (M+1).
