Reaction Conditions

Reaction Steps

A mixture of 8-bromo-11-methyl-6,11-dihydro-5-thia-11-aza-benzo[a]fluorene (270 mg), as prepared in Example 57, and CuCN (270 mg) in DMF (25 ml) was reflux overnight at 170° C. The reaction mixture was filtered through a pad of Celite and then partitioned between saturated NaHCO3 aqueous solution and EtOAc. The aqueous layer was extracted with EtOAc, the organic layers were dried and concentrated to yield crude product. The crude product was purified by chromatography (Hexane:ethyl acetate=5:1) to yield the title compound as a white solid.
