Reaction Steps

To a solution of 1-[trans-3-(hydroxymethyl)cyclohexyl]-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one (180 mg) in dichloroethane (2 ml) was added 1,1,1-tris(acetoxy)-1,1-dihydro-1,2-benziodoxol-3(1H)-one (293 mg) at 4° C. The mixture was stirred at ambient temperature for 2 hours. To the mixture were added chloroform, saturated aqueous sodium hydrogencarbonate and saturated aqueous sodium thiosulfate. The organic layer was separated and extracted with chloroform and washed with water. The extract was dried over MgSO4, filtrated and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel with chloroform:methanol=100:0-85:15 to give trans-3-(2-oxo-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-1(2H)-yl)cyclohexanecarbaldehyde (50 mg).
