Procedure

A mixture of 6-methoxy-3-{2-[3-(2-quinolylmethoxy)benzyl]tetrazolyl}quinolin-2-one (1.00 g, 2.04 mmol), potassium carbonate (564 mg, 4.08 mmol), 1-bromo-3-chloropropane (962 mg, 6.12 mmol), and DMF (100 ml) was stirred for four hours at a bath temperature of 60° C. The solvent of the reaction mixture was removed under reduced pressure. Water was then added to the mixture, and the mixture was extracted with chloroform-methanol (10:1). The thus-obtained organic phase was dried over magnesium sulfate anhydrate, and the solvent was removed under reduced pressure. The organic phase was then subjected to silica gel column chromatography (developer: chloroform-methanol (100:1)), purified, and crystallized from a chloroform-diethylether mixture, to thereby obtain the title compound (546 mg, 0.963 mmol, 47.2%) as pale yellow powder.
