Reaction Steps

To a flask containing ethyl 4-hydroxy-8-iodo-6-(4-morpholinylmethyl)-3-quinolinecarboxylate of Preparation 25 (3.11 g) is added 4-chlorobenzylamine (8.0 mL). The mixture is degassed under reduced pressure. The mixture is placed under an argon atmosphere and is heated at 190° C. for 3 h. The reaction is cooled to room temperature. The excess benzylamine is removed by high vacuum distillation. The residue is crystallized from acetonitrile:methanol (1:1, 800 mL) to yield 3.08 g of the title compound as a white solid:.
