Reaction Steps

To a solution of rel-1-[(3R,4R)-4-methylpiperidin-3-yl]-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one (80 mg), dioxane (1.6 mL) and 4M saturated aqueous sodium hydrogencarbonate (2.4 mL) was added dimethylsulfamoyl chloride (51 mg) at ambient temperature. The mixture was stirred for 2 hours then chloroform (8 mL) was added. The organic layer was separated and dried over MgSO4, filtered, and concentrated in vacuo. The crude residue was purified by silica gel column chromatography to give rel-(3R,4R)—N,N,4-trimethyl-3-(2-oxo-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-1(2H)-yl)piperidine-1-sulfonamide (41 mg) as a colorless solid.
