Reaction Steps

A mixture comprising 10.62 g of N-(7-trifluoromethyl-4-quinolyl)-anthranilic acid sodium salt, 4.98 g of 90% 3-(β-chloroethyl)-oxazolidin-2-one and 60 ml of dimethylformamide was heated under stirring at 120° C. for five hours. Upon completion of the reaction, the mixture was cooled, insoluble sodium chloride was filtered off, and the solvent was evaporated off in vacuo. The residue was treated with 200 ml of water and the solid, collected by filtration, crystallized from methylene dichloride: petroleum ether. 8.7 g of N-(7-trifluoromethyl-4-quinolyl)-anthranilic acid β-(2-oxo-3-oxazolidinyl)-ethyl ester, melting at 124°-125° C., were obtained.
