Procedure
Tyramine (10 mmol), 4,7-dichloroquinoline, and catalytic amounts of potassium iodide were melted in 10 g of phenol at 150° C. for 12 hours. The residue was crystallized with hydrochloric acid from ethyl acetate/water. The product (5 mmol), 3-piperidinopropylchloride hydrochloride (5 mmol), potassium carbonate (15 mmol), and catalytic amounts of potassium iodide were refluxed in N,N-dimethylformamide for 22 hours. The solvent was evaporated and the residue purified by flash chromatography (eluent: ethyl acetate/petroleum ether/triethylamine (95/50/5)). The solvent was removed under reduced pressure. The residue was crystallized with oxalic acid from diethyl ether/ethanol.
