Procedure
To a solution of 4-{[(1S,2R)-2-methylcyclohexyl]amino}-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridine-5-carboxylic acid (3.9 g) and triethylamine (5.11 mL) in dioxane (39 mL) was added diphenylphosphoryl azide (5.0 mL) and the mixture was stirred at 120° C. for 3 hours. To the mixture were added EtOAc and water. The organic layer was separated and extracted with EtOAc. The extract was washed with saturated aqueous sodium hydrogencarbonate and brine, dried over MgSO4, filtrated and evaporated. The residue was purified by column chromatography on silica gel with EtOAc and n-hexane (1:4 to 1:2) to give 1-[(1S,2R)-2-methylcyclohexyl]-6-{[2-(trimethylsilyl)ethoxy]methyl}-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one (3.33 g) as a white powder.
