Abstract
A procedure for the preparation of a quaternary ammonium salt of the formula: **(See formula)** where A is lower alkylene, lower alkenylene, or lower alkadienylene; R1 and R2 are each lower alkyl which can be linked together directly or through an oxygen atom to form a saturated heterocyclic group; R3 is lower alkyl, halo lower alkyl, lower alkynyl, phenylalkyl which may contain one or more halogen atoms as substituents on the phenyl ring, lower alkenyl, hydroxyalkyl lower, carboxyalkyl lower or lower alkenyl-oxyalkyl; R4, R5 and R6 are each lower alkyl of 1 to 3 carbon atoms; X is an acidic residue; and a cyclohexyl ring in the above formula can contain a double bond; whose procedure is characterized by reacting a tertiary amine of the formula: **(See formula)** where A, R1, R2, R4, R5 and R6 are each as defined above and a cyclohexyl ring in the formula above may contain a double bond, with a compound of the formula: R3-X where R3 has the meaning given above.
