METHOD OF PRODUCING N-(1,5,3-DITHIAZEPINAN-3-YL)AMIDES Russian patent published in 2013 - IPC C07D285/36 C07D417/12

Abstract RU 2481338 C1

FIELD: chemistry.

SUBSTANCE: present invention relates to organic chemistry and specifically to a method of producing N-(1,5,3-dithiazepinan-3-yl)amides of general formula (1): where R = p-C₅H₄N (a), (CH₃)₃CO (b), o-CH₃OC₆H₄ (c) which involves reaction of t-butyl-1,5,3-dithiazepinane with a hydrazide of general formula RC(O)NHNH₂ [R is as described above] in the presence of an iron chloride crystalline hydrate catalyst FeCl₃-6H₂O in molar ratio t-butyl-1,5,3-dithiazepinane:RC(O)NHNH₂:FeCl₃-6H₂O=10:10:(0.3-0.7) at temperature of 65-75°C and atmospheric pressure of a mixture of solvents - ethyl alcohol-chloroform for 40-48 hours.

EFFECT: novel method of producing N-(1,5,3-dithiazepinan-3-yl)amides with high selectivity and output, which can be used as biologically active compounds, selective sorbents and extractants of noble and precious metals.
