Reaction Steps

A solution of 4-chloro-6-methoxy-7-(3-morpholinopropoxy)cinnoline hydrochloride (150 mg, 0.36 mmol), (prepared as described for the starting material in Example 12), 4-chloro-2-fluoroaniline (77 mg, 0.53 mmol) in 2-pentanol (4 ml) and 5M isopropanolic hydrogen chloride (1 ml) was heated at 120° C. for 1 hour. The mixture was allowed to cool and isopropanol was added. The resulting precipitate was collected by filtration, washed with ether and dried under vacuum to give 4-(4-chloro-2-fluoroanilino)-6-methoxy-7-(3-morpholinopropoxy)cinnoline hydrochloride (185 mg, 98%).
