ABSTRACT A process for producing a heterocyclic tertiary amine of the formula (III): Image (III) wherein A is a nitrogen atom or C-R5, B is a nitrogen atom or C-R6, Image is a single bond or a double bond, and each of R1, R2, R3, R4, R5 and R6 which may be the same or different, is a hydrogen atom , an acyl group, a halogen atom, a cyano group, etc., provided that two of R1, R2, R3 and R4 may together form a 3-membered, 4-membered, 5- membered or 6-membered aliphatic ring, a heterocyclic ring or aromatic ring, and R7 is a C1-6 alkyl group which may be substituted, etc., which process comprises reacting a heterocyclic secondary amine of the formula (I): Image (I) wherein A, B, Image , R1, R2, R3 and R4 are as defined above, with an alkylating agent of the formula (II): R7 - X (II) wherein R7 is as defined above, and X is a hydroxyl group, a halogen atom, a OSO3R7 group, a OSO2R7 group, a OCO2R7 group, a OCOR7 group, a OP(O)(OR7) group, a OP(O)O(R7)2 group or an amino group, in the presence of a catalyst of Group VIII of the Periodic Table.
