IMPROVED METHOD FOR SYNTHESIS OF NITROISOUREA DERIVATIVES Russian patent published in 2010 - IPC C07C273/00 C07C275/70

Abstract RU 2402528 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method for synthesis of nitroisourea derivatives having general formula (3), in which nitroisourea derivatives of formula (1) and amines of formula (2) or salts thereof react in the presence of a catalytic amount of hydrocarbonate . In formula (1) R₁ is an alkyl group containing 1-4 carbon atoms; in formula (2), R₂ is an alkyl group containing 1-4 carbon atoms, and R₃ is a hydrogen atom; in formula R₁ is an alkyl group containing 1-4 carbon atoms; R₂ is an alkyl group containing 1-4 carbon atoms; and R₃ is a hydrogen atom.

EFFECT: invention enables synthesis of nitroisourea derivatives using a cheap and simple method.
