실험 절차
According to example 30, reacting 7-bromoacetyl-1-ethyl-6-fluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid ethyl ester with 2-(N-acetyl-N-methylamino)thioacetamide in ethanol gave 1-ethyl-6-fluoro-7-[2-(N-acetyl-N-methylaminomethyl)-4-thiazolyl]-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid ethyl ester, mp 173°-175° C. which was then hydrolyzed in refluxing 6N hydrochloric acid to give the title compound, mp 230°-234° C. (dec).
