1-Cyclopropyl-6,7-difluoro-1,4-dihydro-8-methoxy-4-oxo-3-quinolinecarboxylic acid Chemical Properties,Usage,Production

Chemical Properties

Off-White to Light-Yellow Powder

Uses

Moxifloxacin intermediate.

Synthesis

112811-71-9

112811-72-0

General Steps: Reaction: in a 250 mL round bottom flask, 10 g of ethyl 1-cyclopropyl-6,7-difluoro-8-methoxy-4-yloxy-1,4-dihydroxyquinoline-3-carboxylate (compound of formula 2) and 100 mL of anhydrous methanol were added and stirred until completely dissolved. Subsequently, 13.3 mL of 36% hydrochloric acid was added slowly and dropwise. After addition, the reaction system was heated to 65 °C and the reaction was stirred at this temperature for 15 hours. Post-treatment: after completion of the reaction, the system was cooled to 10 °C and stirring was continued for 2 hours to promote crystallization. Subsequently, the system was filtered under reduced pressure. The filter cake was washed with 20 mL of anhydrous methanol and subsequently dried under vacuum at 60 °C for 8 h to afford 8.86 g of 1-cyclopropyl-6,7-difluoro-1,4-dihydro-8-methoxy-4-oxo-3-quinolinecarboxylic acid (compound of formula 3) in 96.83% yield.
