実験手順

8-(3-Amino-3-methyl-1-azetidinyl)-7-fluoro-1-methoxy-4-oxo-1,4-dihydrobenzo[b][1,8]naphthyridine-3carboxylic acid was prepared under the conditions of Example 15, but starting with 1.53 g of 7,8-difluoro-1-methoxy-4-oxo-1,4-dihydrobenzo[b][1,8]naphthyridine-3carboxylic acid and 2.22 g of 3-amino-3-methylazetidine dimethane-sulphonate. 1.27 g of 8-(3-amino-3-methyl-1-azetidinyl)-7-fluoro-1-methoxy-4-oxo-1,4-dihydrobenzo[b][1,8]naphthyridine-3-carboxylic acid are obtained in the form of a yellow solid, which decomposes at 346° C.
