Reaction Conditions

Reaction Steps

A mixture of 0.15 g of 4-hydroxy-6-[(phenylmethyl)thio]-7-(trifluoromethyl)-3-quinolinecarboxylic acid and 1.2 mL of dimethylformamide is treated with 0.075 g of carbonyldiimidazole. The mixture is stirred 20 h at 35-40° C. The solution is cooled to 25° C. and it is treated with 0.075 mL of distilled water and then it is stirred for 10 min. The solution is treated with 0.053 mL of 4-chlorobenzylamine and it is stirred for 18 h. The mixture is diluted with 1.0 mL of distilled water and then it is decanted from a dark, oily precipitate. This precipitate is treated with 1 mL of glacial acetic acid and the mixture is shaken for 5 min. The solid which formed is collected by filtration and it is washed with a few mL of 50% aqueous acetic acid. The solid is dried in a stream of air to give 48 mg of the title compound.
