    • A process for producing a heterocyclic tertiary amine of the formula (III): ##STR1## wherein A is a nitrogen atom or C-R.sup.5, B is a nitrogen atom or C-R.sup.6, is a single bond or a double bond, and each of R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 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 R.sup.1, R.sup.2, R.sup.3 and R.sup.4 may together form a 3-membered, 4-membered, 5-membered or 6-membered aliphatic ring, a heterocyclic rig or aromatic ring, and R.sup.7 is a C.sub.1-6 alkyl group which may be substituted, etc., which process comprises reacting a heterocyclic secondary amine of the formula (I): ##STR2## wherein A, B, , R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as defined above, with an alkylating agent of the formula (II):R.sup.7 --X (II)wherein R.sup.7 is as defined above, and X is a hydroxyl group, a halogen atom, a OSO.sub.3 R.sup.7 group, a OSO.sub.2 R.sup.7 group, a OCO.sub.2 R.sup.7 group, a OCOR.sup.7 group, a OP(O)(OR.sup.7) group, a OP(O)O(R.sup.7).sub.2 group or an amino group, in the presence of a catalyst of Group VIII of the Periodic Table.
