Reaction Conditions

Reaction Steps

To a flask containing ethyl 1-cyclopropyl-6-iodo-4-oxo-1,4-dihydro-3-quinolinecarboxylate from Preparation No. 19 (0.19 g) is added p-chlorobenzylamine (1.0 mL). The reaction is tightly capped and heated to 180° C. for 1 hour. The reaction is cooled to room temperature and partioned between dichloromethane containing methanol and dilute hydrochloric acid. The aqueous layer is extracted with dichloromethane and the combined organic layers are washed with brine, dried and concentarted under reduced pressure. The residue is adsorbed onto silica and chromatographed on silica eluting with 2% to 6% methanol in dichloromethane. The product containing fractions are evaporated to give 0.10 g of the title compound as a tan solid.
