Procedure

A mixture of 500 mg 6-bromo-4-chloroquinoline, 330 mg 4-methoxypiperidine monohydrochloride, 0.57 mL triethylamine and 10 mL N,N-dimethylformamide was stirred at 130° C. for 8 hours. Ethyl acetate and water were added to the reaction solution, and the organic layer was separated. The organic layer was washed with water and brine and dried over sodium sulfate, and the solvent was evaporated. The residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give 516 mg of the title compound as a pale yellow oil.
