METHOD OF OBTAINING BENZYLAMINE DERIVATIVE AND ACYLBENZYLAMINE DERIVATIVE Russian patent published in 2009 - IPC C07C209/62 C07C211/29 C07C271/18 C07C269/04 C07C231/12 C07C233/31 

FIELD: chemistry.

SUBSTANCE: invention relates to novel improved method of obtaining benzylamine derivative of general formula (3)

and method of obtaining from the latter of carbamate derivative of general formula (6) where X¹ represents halogen atom and R¹ represents acyl group selected from C₁-C₇-linear or branched aliphatic acyl group, C₃-C₆-cycloalkylcarbonyl group, and aromatic acyl group, R³ represents alkyl group. Methods include interaction of benzyl derivative of general formula (1)

with halogen compound of general formula (2): where X² represents halogen atom, and R² represents acyl group selected from C₁-C₇-linear or branched aliphatic acyl group, C₃-C₆-cycloalkylcarbonyl group, and aromatic acyl group, in presence of Lewis acid. From obtained compound of general formula (3) carbamate derivative of general formula (6) is obtained. For this purpose compound of general formula (3) is subjected to hydrolysis obtaining aminoderivative of general formula (4)

which is further subjected to interaction with ester of halogen-formic acid of general formula (5) where X¹ and R² are determined above, X³ represents halogen atom, and R³ represents alkyl group, in presence of base. Invention also relates to novel acylbenzylamine derivatives of general formula (7):

where X¹ represents halogen atom, each of R² and R⁴ independently represents C₁-C₇-linear or branched aliphatic acyl group, C₃-C₆-cycloalkylcarbonyl group, and R can additionally represent hydrogen atom. Benzylamine derivatives of formula (3) and formula (7) can be used as intermediate products for obtaining agricultural or garden bactericide based on formula (6) carbamate.

EFFECT: elaboration of improved method of obtaining benzylamine derivative.
