METHOD OF PRODUCING N-[4-(THI)OXO-1,3,5-TRIAZINAN-1-YL]ARYLAMIDES Russian patent published in 2015 - IPC C07D251/08 C07D401/12

Abstract RU 2551688 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing N-[4-(thi)oxo-1,3,5-triazinan-1-yl]arylamides of general formula (1), where R=m-C₅H₄N, o-MeOC₆H_4,m-MeOC₆H₄,X=O, S, which includes reacting N,N'-bis[dimethylaminomethyl](thio)urea of general formula (Me)₂NCH₂C(X)CH₂N(Me)₂, where X=S, O, with a hydrazide of general formula RC(O)NHNH₂ in the presence of a samarium chloride crystalline hydrate catalyst SmCl₃·6H₂O with molar ratio N,N'-bis[dimethylaminomethyl](thio)urea:RC(O)NHNH₂:SmCl₃·6H₂O=10:10:(0.8-1.2) in ethanol at 75-85°C and atmospheric pressure for 22-26 hours.

EFFECT: obtaining novel N-[4-(thi)oxo-1,3,5-triazinan-1-yl]arylamides.
