The present invention relates to a process for N-alkylation of nitrogenous organic compounds.n n n According to this process, the nitrogenous organic compound is reacted comprising, bound to the nitrogen atom, a labile hydrogen with an alkylating agent in the presence on the one hand, of an inorganic base and, on the other hand, of a sequestering agent of general formula: in which n is an integer greater than or equal to 0 and less than or equal to 10 (0 ≤ n ≤ 10), R 1 , R 2 , R 3 , R 4 identical or different represent a hydrogen atom or an alkyl radical having from 1 to 4 carbon atoms and R 5 represents an alkyl or cycloalkyl radical having from 1 to 12 carbon atoms, a phenyl radical or a radical of formula -C m H 2m -φ, or C m H 2m +1 - φ-, m being between 1 and 12. |
