Participants

Reaction Steps

To a suspension of 1-[(3R)-3-piperidinyl]-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one dihydrochloride (30 mg) and 1-hydroxybenzotriazole (18.4 mg) in N,N-dimethylformamide (0.72 mL) was added triethylamine (0.028 mL), 2-thiophenecarboxylic acid (15.1 mg), and WSCD.HCl (70 mg, 0.365 mmol). After stirring for 9 hours at ambient temperature, the reaction mixture was diluted with EtOAc, washed with saturated aqueous sodium hydrogencarbonate, water (×3), and brine, dried over MgSO4, evaporated in vacuo. The residue was purified by silica gel column chromatography (chloroform:methanol=20:1) to give 1-[(3R)-1-(2-thienylcarbonyl)-3-piperidinyl]-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one (24.0 mg) as a white crystals.
