Organonitrogen compounds bearing a labile hydrogen atom directly bonded to a reactive nitrogen function, e.g., nitrogen heterocycles or substituted anilines, are N-alkylated with an N-alkylating agent in the presence of inorganic base and at least one sequestering agent having the structural formula: N-CHR1-CHR2-O-(CHR3-CHR4-O)n-R5]3 (I) wherein n is a number ranging from 0 to 10, R1, R2, R3, R4, which may be identical or different, each represents a hydrogen atom or an alkyl radical having 1 to 4 carbon atoms, and R5 represents an alkyl or cycloalkyl radical having 1 to 12 carbon atoms, a phenyl radical, or a radical of the formula -CmH2m- phi , or CmH2m+1- phi -, m ranging from 1 to about 12 and phi being phenyl. |
