실험 절차

To an efficiently stirred and gently cooled 4.2 ml mixture of thionyl chloride (“SOCl2”) and 1.05 ml of pyridine (“Py”) at −3° C. was added 1.015 g (3.708 mmol) of 3-chloromethylsulfinyl-7-fluoro-1-methyl-4-quinolone (monochloroflosequinan) (Compound 1 of FIG. 1). This addition was made in multiple alloquots over a period of approximately 1 min. During this addition, cooling was applied to keep the temperature in the range 0-5° C.
