Reaction Steps
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-ethylamino)thioacetamide in ethanol gave 1-ethyl-7-[2-[(N-acetyl-N-ethylamino)methyl]-4-thiazolyl]-6-fluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid ethyl ester, mp 160°-161° C. which was then hydrolyzed in refluxing 6N hydrochloric acid to afford the title compound, mp 289°-300° C. (dec).
