METHOD OF SYNTHESIS OF SECONDARY AMINES Russian patent published in 2000 - IPC

Abstract RU 2148055 C1

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method of synthesis of secondary amines from the corresponding sulfamides. Secondary amines are used in organic synthesis, production of biologically active substances, drugs and analytical reagents and chelating compounds. Method involves hydrolysis of N,N-disubstituted sulfamides with 20-30% sulfuric acid in teflon autoclave under condition of microwave field effect at power 350 W for 0.5 h. EFFECT: simplified conditions of hydrolysis, decreased reaction time, increased yield and purity of secondary amine. 8 ex
