Reaction Conditions

Reaction Steps

3-amino-4-(benzylamino) quinoline (9.5 g; 0.038 mol) and glycolic acid (6.8 g; 0.089 mol) were mixed and the mixture was heated at 150° C. for about 4 hr. The dark mixture was then dissolved in dilute hydrochloric acid with heating. Upon cooling a precipitate formed and was filtered from the mixture. The solid was dissolved in hot water. The solution was then made basic with ammonium hydroxide to precipitate the product. A second, less pure, small crop was obtained from the original filtrate by making it basic with ammonium hydroxide. The solid was triturated in ethyl acetate to give a green colored powder. Total yield was 82%. The product was recrystallized from methanol to give a pure sample m.p. 211°-213° C.
