Reaction Steps

A mixture of 2,3-dimethyl-3H-imidazo[4,5-f]quinoline (0.40 g, 2.03 mmol) and platinum(IV) oxide (24 mg, 0.11 mmol) in HCl (6 N, 2 mL) and ethanol (10 mL) was stirred at room temperature under H2 for 24 h. Then ethanol was removed under reduced pressure and the residue was dissolved in EtOAc (20 mL) and sat. NaHCO3 (3 mL), filtered through Celite, washed with EtOAc (10 mL×3), and separated. The water layer was then extracted with EtOAc (10 mL×3). The combined organic layers were dried with Na2SO4 and filtered; and the solvent was removed under reduced pressure to give a yellow solid. The residue was used in the next step without further purification (320 mg). MS (ESI): m/z 202 [M+H]+.
