Participants

Reaction Steps

To a suspension of N-(3-(5-(4-chlorophenyl)-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-2,4-difluorophenyl)-propane-1-sulfonamide (0.2 g, 0.41 mmol) in dioxane (15 mL) were added ethyl chloroformate (EtOCOCl, 44 mg, 0.41 mmol) and triethylamine (0.14 g, 1.38 mmol). The reaction was stirred at rt for 1.5 h, then concentrated in vacuo. The residue was purified by a silica gel column chromatography (hexane/EtOAc (v/v)=4/1) to afford the title compound as a white solid (0.12 g, 50%). The title compound was characterized by LC-MS and 1H NMR as shown below:
