Abstract

The invention relates to the replacings of aniline, especially to the obtaining of C1-C4-alkylanilin fumarate-semiproduct for the synthesis of heterocyclic herbicides. Its purpose is to simplify the process. It is done through the reaction C1-C4 of alkyl dichlorsuccinate, at the beginning with a treble surplus of amine with formula R1R2NH wherein R1 and R2 represent H, C1-C4-alkyl, from which only one of R1 and R2 representing H or NR1-R2 being heterocycle with 5 or 6 member with 1,2 heteroatoms, at ebullition during 8 hours, than with aniline in organic inert dissolvent, which contains organic acide, at 80-85°C during 4 hours. In this case is possible the using of reactives easy of access and the obtaining of efficiency of destination product (until 69%).
