FIELD: chemistry.
SUBSTANCE: described is a novel method for selective production of 5-alkyl-1,3,5-triazinan-2(thi)ones of general formula 
, where X=O, S; Alkyl=t-Bu, cyclohexyl; R=H, allyl, involving reaction of N,N-bis(methoxymethyl)alkylamine of general formula Alkyl-N(CH2OMe)2, where Alkyl has values given above, with (thio)urea of general formula H2NC(X)NHR, where X and R are given above, in the presence of samarium chloride crystalline hydrate SmCl3·6H2O catalyst in molar ratio Alkyl-N(CH2OMe)2:(thio)urea:SmCl3·6H2O = 10:10:(0.3-0.7) at temperature of 60°C and atmospheric pressure in a mixture of solvents CHCl3-EtOH (1:1, by volume) for 6-10 hours.
EFFECT: obtained compounds have potential for use as effective pesticides and can also serve as synthons for producing alkaloid Agelastatina A.
