Procedure
71.6 g of 1-(2,2,2-trichloroethoxycarbonyl)-6-trifluoromethyl-1,2-dihydroquinoline-2-phosphonic acid diethyl ester is dissolved in 800 ml of ethanol, mixed with 3.6 g of platinum(IV)-oxide and hydrogenated at normal pressure. It is filtered, concentrated by evaporation and recrystallized from isopropyl ether.
