FIG. 9 depicts the second step in the synthesis of e.e.(S)-(+)-3-chloromethylsulfinyl-7-fluoro-1-methyl-4-quinolone and (R)-(−)-3-chloromethylsulfinyl-7-fluoro-1-methyl-4-quinolone. In this step, 7-fluoro-1-methyl-3-methylthio-4-quinolone is chlorinated as described to produce 3-chloromethylthio-7-fluoro-1-methyl-4-quinolone.
