Reaction Steps

A solution of 1-(1-fluoromethyl-1-methyl-2-fluoroethyl)-6,7-difluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid (400 mg, 1.26 mmol), (1S,6R)-2-oxa-5,8-diazabicyclo[4.3.0]nonane (176 mg, 1.39 mmol) and 1,4-diazabicyclo[2.2.2]octane (141 mg, 1.26 mmol) in absol. acetonitrile (20 ml) is heated under reflux overnight. After cooling the reaction mixture to room temperature, the precipitated crystals are filtered off and washed with acetonitrile.
