실험 절차

50% hydrogen peroxide (57 ml, 33.6 mg, 0.988 mmol) was added to a solution of 3-carboxymethylthio-7-fluoro-1-methyl-4-quinolone (4) in acetic acid (3.6 ml) at 60° C. and the mixture was stirred at 55° C. for 4 h. The hot mixture was diluted with water (12 ml) and cooled to 0° C. A white solid that precipitated was filtered off and dried under high vacuum. The yield of 3-Carboxymethylsulfinyl-7-fluoro-1-methyl-4-quinolone was 185 mg (72.7%) (5).
