Procedure

A mixture of 1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid (0.4 g), anhydrous acetonitrile (4 ml), trans-3-t-butoxycarbonylamino-4-methylpyrrolidine (0.43 g) and DBU (0.22 g) was refluxed for an hour. After cooling, the resulting precipitate was collected by filtration and washed with acetonitrile and ethanol successively to give 7-(trans-3-t-butoxycarbonylamino-4-methyl-1-pyrrolidinyl)-1-cyclopropyl-6,8-difluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid (0.34 g) as white yellowish powder, mp 237°-240° C. (decompd.).
