title: One-step synthesis of 6-acetamido-3-(N-(2-(dimethylamino) ethyl) sulfamoyl) naphthalene-1-yl 7-acetamido-4-hydroxynaphthalene-2-sulfonate and its characterization with 1D and 2D NMR techniques.
abstract: A one-step method was reported for the synthesis of 6-acetamido-3-(N-(2-(dimethylamino) ethyl) sulfamoyl) naphthalene-1-yl 7-acetamido-4-hydroxynaphthalene-2-sulfonate by treating 7-acetamido-4-hydroxy-2-naphthalenesulfonyl chloride with equal moles of N, N-dimethylethylenediamine in acetonitrile in the presence of K2CO3. The chemical structure of the obtained compounds was characterized by MS, FTIR, (1)H NMR, (13)C NMR, gCOSY, TOCSY, gHSQC, and gHMBC. The chemical shift differences of (1)H and (13)C being δ 0.04 and 0.2, respectively, were unambiguously differentiated.
