Procedure

A mixture of 8-(benzyloxy)-4-chloro-7-methoxybenzo[g]quinoline-3-carbonitrile (1.00 g, 2.7 mmol), 2-chloro-4-fluoro-5-methoxyaniline (560 mg, 3.2 mmol), tris(dibenzylideneacetone)dipalladium(0) (240 mg, 0.26 mmol), 2-dicyclohexylphosphino-2′-(N,N-dimethylamino)biphenyl (330 mg, 0.84 mmol) and K3PO4 (860 mg, 4.1 mmol) in 15 mL of ethylene glycol dimethyl ether is heated at 80° C. for 3 hours. An additional 5% of all reagents is added and the mixture is heated at 80° C. for 2 hours then cooled to room temperature and partitioned between aqueous sodium bicarbonate and methylene chloride. The organic layer is dried over magnesium sulfate, filtered and concentrated in vacuo. Purification by column chromatography eluting with 1:1 hexane/ethyl acetate yields 500 mg (36%) of 8-(benzyloxy)-4-[(2-chloro-4-fluoro-5-methoxyphenyl)amino]-7-methoxybenzo[g]quinoline-3-carbonitrile as a yellow solid, mp 248-250° C. dec.
