Reaction Steps

A solution of 9-{4-[(tert-butoxycarbonylamino)methyl]phenyl}-4-oxo-4,5-dihydrothieno[2,3-c]quinolin-8-yl trifluoromethanesulfonate (176 mg, 0.320 mmol), zinc chloride (75 mg, 0.640 mmol), 1,1′-bis(diphenylphosphino)ferrocene (18 mg, 0.032 mmol), and tris(dibenzylideneacetone)dipalladium(0) (15 mg, 0.016 mmol) in anhydrous DMF (4 mL) was heated at 130° C. for 3 h. The reaction mixture was cooled, quenched with water and the resulting precipitate was filtered and purified by column chromatography (silica, methanol/methylene chloride gradient) to afford the desired product (120 mg, 87%) as a brown solid: ESI MS m/z 432 [C24H21N3O3S+H]+.
