Reaction Steps

An activated manganese dioxide (108 mg, 1.25 mmol) was added to a solution of 1-(1-ethylpropyl)-6-mesityl-4-methyl-2,3-dihydro-1H-pyrrolo[3,2-c][1,7]naphthyridine (93 mg, 0.25 mmol) in toluene (9.0 mL) and methylene chloride (3.0 mL) and the mixture was heated under reflux for three days. After filtering through Celite, the mixture was evaporated. The residue was purified by silica gel column chromatography (10% ethyl acetate/hexane), to give the title compound (55 mg) as pale brown crystals.
