Reaction Steps

2-(N-Acetylaminomethyl)-5-methyl-2,3,6,7-tetrahydrofuro[2,3-f]quinoline-7-one (750 mg) was suspended in acetic acid (15 ml), to which 2,3-dichloro-5,6-dicyano -1,4-benzoquinone (782 mg) was added. The mixture was stirred at 60° C. for 1 hour. The solvent was distilled off under reduced pressure. To the residue, aqueous 1N NaOH solution (50 ml) was added. Precipitated crystals were collected. As a result, 553 mg of 2-(N-acetylaminomethyl) -6,7-dihydro-5-methylfuro[2,3-f]quinoline-7-one (74.3%) was obtained.
