Procedure

To a solution of ethyl 4-{[(1S,2R)-2-methylcyclohexyl]amino}-1H-pyrrolo[2,3-b]pyridine-5-carboxylate (3.8 g) in N,N-dimethylformamide (76 mL) was added 60% sodium hydride (580 mg) at 4° C. The mixture was stirred at the same temperature for 1 hour. To the mixture was added [2-(chloromethoxy)ethyl](trimethyl)silane (2.55 mL) and the solution was stirred at ambient temperature for 1 hour. To the solution was added water and EtOAc. The mixture was extracted with EtOAc and washed with brine. The extract was dried over MgSO4, filtrated and evaporated. The residue was purified by column chromatography on silica gel with EtOAc and n-hexane (1:3 to 1:1) to give ethyl 4-{[(1S,2R)-2-methylcyclohexyl]amino}-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridine-5-carboxylate (5.4 g) as a pale yellow oil.
