Reaction Steps

8-Methoxy-6,11-dihydro-5-thia-11-aza-benzo[a]fluorene (79 mg, 0.281 mmoL) in DMF (5 mL) was treated with KO-t-Bu (1.0 M in THF, 0.48 mL, 0.48 mmoL) under a flow of O2 for 6 hours. The reaction mixture was then partitioned between water and EtOAc. The EtOAc layer was washed with saturated NH4Cl, water, brine, dried over anhydrous Na2SO4, filtered and concentrated to yield a brown oil. The crude material (the oil) was then purified by column chromatography (silica gel, CH2Cl2: MeOH 9:1 as eluent) to yield the title compound as a white solid.
