Abstract
FIELD: organic chemistry. SUBSTANCE: product: N,N-dialkylsubstituted of 1-nitronaphthelene-5-sulfamides in which the NRR-residue of aminomethylpropylamine, methylisopropylamine, methylbutylamine, ethylcyclohexylamine, morpholine or azepine can be used for synthesis as semiproducts for synthesis of 1-aminonaphthalene-5-sulfamides. Synthesis is carried out by reaction of 1-nitronaphthalene sulfochloride with corresponding amine in the presence of sodium carbonate in the medium of toluene as a solvent. Method involves elimination of high cost trifluoroacetic anhydride and decreased cost for purification. EFFECT: synthesis of new semiproducts, increased yield, decreased cost. 1 dwg, 5 tbl
