Following the procedure of Example 3, the reaction mixture of 141.8 mg (0.60 mmol) of 4-chlorobenzo[g]quinoline-3-carbonitrile, 102.9 mg (0.60 mmol) of 4-chloro-5-methoxy-2-methylaniline (can be prepared by the procedure disclosed in WO 85/01939, which is hereby incorporated by reference) and 57.8 mg (0.50 mmol) of pyridine hydrochloride in 8.0 mL of 2-ethoxyethanol is heated at 130–135° C. for 1.5 hours to yield the crude product. Purification of the crude product on preparative TLC (developing solvent: 95:5 methylene chloride/methanol) yields 159.3 mg (72.2%) of the pure product as a yellow solid, mp 195–197° C.
