Procedure

To a mixture of 6-methoxy-3-{2-[3-(2-quinolylmethoxy)benzyl]tetrazolyl}quinolin-2-one (1.61 g, 3.30 mmol) and potassium carbonate (684 mg, 4.95 mmol), was added DMF (30 ml). Methyl iodinate (562 mg, 3.96 mmol) was added dropwise to the resultant mixture, and thereafter stirred for four hours at a bath temperature of 80° C. The solvent of the reaction mixture was removed under reduced pressure. Water was added to the mixture, and the organic phase was extracted therefrom with a mixture of chloroform-methanol (10:1). The organic phase was dried over sodium sulfate anhydrate, subjected to silica gel column chromatography (with chloroform-methanol (50:1)), and concentrated under reduced pressure. The resultant residue was recrystallized from a chloroform-n-hexan-ether mixture, to thereby obtain the title compound (1.35 g, 2.68 mmol, 81.1%) as pale yellow powder.
