PROCEDURE

实验过程

7-Fluoro-1-methyl-4-oxo-8-(1-piperazinyl)-1,4-dihydro-benzo[b][1,8]naphthyridine-3-carboxylic acid is prepared under the conditions of Reference Example 1 but starting from 10 g of 8-chloro-7-fluoro-1-methyl-4-oxo-1,4-dihydro-benzo[b][1,8]naphthyridine-3-carboxylic acid and 28 g of piperazine in 100 cm3 of pyridine. 5.5 g of 7-fluoro-1-methyl-4-oxo-8-(1-piperazinyl)-1,4-dihydro-benzo[b][1,8]naphthyridine-3-carboxylic acid hemihydrate are obtained in the form of a yellow solid melting at 370°-375° C.
