Procedure
To a solution of 2-methanesulfonyloxymethyl-5-methyl -2,3,6,7-tetrahydrofuro[2,3-f]quinoline-7-one (931 mg) in dimethylformamide (20 ml), sodium iodate (4.5 g) was added, and the mixture was stirred at 100° C. for 2 hours. After completion of the reaction, the solvent was distilled off, and the residue was purified by silica gel column chromatography (eluent: chloroform) to obtain 1 g (assayed quantitatively) of the target compound as a light yellow powder.
