Versuchsvorschrift

Part of the product of the above procedure, that is, 9-cyano acridine (4 g) is dissolved in sulphuric acid containing 10% by weight of distilled water (total volume equals 40 cm3). The mixture thus obtained is heated at a temperature of 100° C. for 2 hours after which time sodium nitrite (10.7 g) is added slowly with continuous stirring. The resulting mixture is heated at 100° C. for 2 hours then poured into cold, distilled water (650 cm3) The solid material which precipitates at this stage is isolated by filtration and allowed to dissolve in the minimum quantity of one molar sodium hydroxide solution; the solution thus obtained is filtered and the filtrate made slightly acidic by the addition of a 50%, by volume, solution of sulphuric acid in water. The 9-carboxy-acridine so formed is then dried in vacuo.
