Participants

Reaction Steps

To a solution of N-(3-(5-(4-chlorophenyl)-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-2,4-difluorophenyl)propane-1-sulfonamide (5 g, 10.2 mmol) in THF (36 mL) was added KOH (1.1 g, 20.4 mmol). The reaction was stirred at rt for 0.5 h, followed by the addition of a solution of 1-chloroethyl cyclohexyl carbonate (2.3 g, 11.2 mmol) in THF (9 mL). The mixture was refluxed for 16 h, then cooled to rtand diluted with THF (50 mL). The resulting mixture was filtered and the filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (v/v)=8/1) to give the title compound as a white solid (3.49 g, 51.9%). The title compound was characterized by LC-MS and 1H NMR as shown below:
