Reaction Conditions

Reaction Steps

A mixture of 397 mg of 7-(2-chloromethylmorpholino)-1-ethyl-6,8-difluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid, 156 mg of pyrrolidine, 150 mg of sodium iodide and 15 ml of dimethylformamide is stirred at 150° C. for 7 hours. The reaction mixture is concentrated under reduced pressure and to the residue is added water followed by extracting with chloroform. The organic layer is washed with water, dried over anhydrous magnesium sulfate and then the solvent is distilled off to give 1-ethyl-6,8-difluoro-1,4-dihydro-4-oxo-7-[2-(1-pyrrolidinylmethyl)morpholino]quinoline-3-carboxylic acid.
