Reaction Steps

23.16 Grams (0.1 mole) of 4-chloro-8-trifluoromethyl quinoline were dissolved in 22 milliliters of concentrated hydrochloric acid and 150 milliliters of water and the solution was added in a stream to a vigorously stirred solution of 13.7 grams (0.1 mole) of p-aminobenzoic acid in 150 milliliters of water at 60° C. The mixture was heated at 90° C. for 2 hours, cooled, and the solid collected and recrystallized from ethanol to give 32.1 grams (83%) of the title compound as the hydrochloride monohydrate, melting point 262°-265° C.(d).
