Procedure
3-Fluoropyridine hydrochloride (240 mg) and sodium carbonate (250 mg) were added to a dimethylformamide solution of 2-({5-chloro-2-[(1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)carbamoyl]phenyl}amino)ethyl methanesulfonate (595 mg), followed by stirring at 40° C. for 15 hours. Water was added to the reaction liquid, followed by extraction with chloroform. The organic layer was dried with magnesium sulfate and then the solution was concentrated under a reduced pressure. The resulting residue was purified by silica gel column chromatography (basic silica gel, chloroform:methanol, 1:0 to 95:5). By treating the resulting free base with 4 M hydrogen chloride/ethyl acetate solution, 4-chloro-2-{[2-(3-fluoropyrrolidin-1-yl)ethyl]amino}-N-(1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)benzamide hydrochloride (156 mg) was obtained as a solid.
