Reaction Steps

Analogous to example 6 but utilizing 5.56 g (13.85 m Mol) of the mixed anhydride of 7-chloro-6-fluoro-1-(2,4-difluorophenyl)1,4-dihydro-4-oxoquinoline-3-carboxylic acid and difluoroboronic acid, 5.82 g (16.62 m Mol) 2-benzyl-2,5-diazabicyclo(2.2.1)heptane dihydrobromide and 11.58 ml (83 m Mol)triethylamine in 50 ml dry DMSO yielded 2.73 g (39%) of the product, mp 233° C.-238° C. dec.
