Reaction Steps

The title compound was prepared according to the procedure as described in Example 26 step 2 using N-(3-(5-(4-chlorophenyl)-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-2,4-difluorophenyl)propane-1-sulfonamide (0.3 g, 0.61 mmol), KOH (69 mg, 1.23 mmol) in anhydrous DMF (2 mL), a solution of TBAB (396 mg, 1.23 mmol) in anhydrous DMF (0.5 mL) and a solution of 1-chloroethyl isopropyl carbonate (101 mg, 0.61 mmol) in anhydrous DMF (0.5 mL). The crude product was purified by a silica gel column chromatography (PE/EtOAc (v/v)=5/1), and recrystallized in methanol to afford the title compound as a white solid (42 mg, 11.1%). The title compound was characterized by LC-MS and 1H NMR as shown below:
