Octahydropyrrolo[3,4-b]pyrrole → 7-(2,7-Diazabicyclo[3.3.0]octan-7-yl)-8-chloro-1-cyclopropyl-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid

Participants

Reaction Steps

650 mg (2.3 mmol) of 8-chloro-l-cyclopropyl-7-fluoro-1,4 -dihydro-4 -oxo-3 -quinolinecarboxylic acid together with 315 mg (2.8 retool) of 2,7-diazabicyclo[3.3.0]octane and 510 mg (4.6 mmol) of 1,4-diazabicyclo[2.2.21]octane are heated for six hours at 120° C. in 23 ml of dimethyl sulphoxide. All volatile components are removed under a high vacuum, and the residue is stirred thoroughly with acetonitrile and dried at approximately 100° C.
