A process for producing a heterocyclic tertiary amine of the formula (III):
wherein A is a nitrogen atom or C-R⁵, B is a nitrogen atom or C-R⁶, ---- 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):
wherein A, B, ----, 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.
