실험 절차
A solution of 21.9 g of ethyl 4-chloro-7,8-difluoroquinoline-3-carboxylate in 7300 cm3 of ethanol in the presence of 8.8 g of triethylamine and 2.2 g of 5% palladium on carbon was hydrogenated at atmospheric pressure for 1 hour. The solid residue obtained was recrystallized from 300 cm3 of hexane. 17.6 g of ethyl 7,8-difluoroquinoline-3-carboxylate was obtained in the form of white crystals, which melted at 118° C.
