Abstract:
PURPOSE: A method for synthesizing CH_2CN group-introduced N-(3-cyanopropyl)sulfonamide derivatives is provided to ensure high reactivity and to easily convert into hydrophilic amine group. CONSTITUTION: A N-(3-cyanopropyl)benzothiazolesulfonamide which is used in synthesizing medical products, amino acids, and diamine derivatives has a structural formula 1. A N-(3-cyanopropyl)sulfonamide derivative is synthesized by reacting CMBP((Cyanomethylene)tri-n-butylphosphorane) with OH functional group of aminoethanol of structural formula 2. The synthesis is performed under the presence of benzene or toluene.
