This compound has unique chemical properties. The synthetic route is as follows. Recommanded Product: 2002-24-6
9-(2′-hydroxyethylamino)-4-methyl-1 -nitroacridine 4-Methyl-1-nitro-9-phenoxyacridine (0.33 g) is dissolved in phenol (10 g), ethanolamine hydrochloride (0.2 g) is added and the mixture is heated at 80 C. for 0.5 hour. The reaction mixture is cooled to room temperature, diluted with ether, slowly poured into dry ether (200 ml) and acidified with ethereal solution of hydrogen chloride. The resulting precipitate is filtered off, washed with ether and crystallized from absolute ethanol to give 9-(2′-hydroxyethylamino)-4-methyl-1-nitroacridine monohydrochloride as orange crystals (0.27 g, 84%), m.p. 238 C. (decomp.) 1H NMR (d6DMSO): delta2.45 (s, 3H, CH3), 3.48 (q, 2H, H-2′), 3.65 (t, 2H, H-1′), 4.3 (t, 1H, OH), 7.1 (t, 1H, H-7), 2), 7.35 (d, 1H, J=7.8 Hz, H-3), 7.5 (t, 1H, H-6), 7.65 (d, 1H, J=8 Hz, H-5), 7.75 (d,1H, J=8.0 Hz, H-8).
