실험 절차

A mixture of ethyl 4-chloro-7-(trifluoromethyl)-3-quinoline-carboxylate (3.04 g) and 4-aminobenzoic acid (1.37 g) in tetrahydrofuran (53 ml) was stirred under reflux for 10 hours and cooled to room temperature. The precipitates were collected and washed with tetrahydrofuran to give 4-[[3-ethoxycarbonyl-7-(trifluoromethyl)-4-quinolyl]amino]benzoic acid hydrochloride (2.69 g) as yellow powder.
