Procedure
3.27 g of 4-chloro-quinoline, 1.38 g of 1H-1,2,4-triazole and 0.21 g of 1H-1,2,4-triazole hydrochloride are mixed in 10 ml of dimethyl-formamide for 1 hour at 80° C. The reaction mixture is added to 50 ml of water, neutralized with cc. aqueous ammonia, the precipitate is filtered, washed with water and recrystallized from 15 ml of ethanol. 2.47 g /63%/ of 4-(1H-1,2,4-triazole-1-yl)-quinoline (Substance 1) are obtained. M.p.:147°-149° C.
