実験手順

In place of 3-acetylaminopyrrolidine, 3-benzyloxycarbonylaminopyrrolidine was allowed to react with 7-chloro-1-ethyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid in the same manner as described in Example 1 to give 7-(3-benzyloxycarbonylamino-1-pyrrolidinyl)-1-ethyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid, which was used in the next step:
