A method for producing azoniaspironortropine ester halide compounds of the formula I where X is a halogen atom, R 1 is selected from the group consisting of optionally substituted alkylene group, optionally substituted alkenylene group and the group -R-Z-R-, where each R, independently of the others, is a covalent bond, an optionally substituted alkylene group or an optionally substituted alkenylene group, where both R groups may not be a covalent bond at the same time, and Z is an optionally substituted cycloalkyl group, an optionally substituted heterocyclyl group, an optionally substituted aryl group or an optionally substituted heteroaryl group, R 2 and R 3, independently of one another, are selected from the group consisting of hydrogen, optionally substituted alkyl group and optionally substituted cycloalkyl group, and R 4 and R 5, independently of one another, are selected from the group consisting of hydrogen, halogen atom, optionally substituted alkyl group, optionally substituted alkenyl group, optionally substituted cycloalkyl group, optionally substituted heterocyclyl group, optionally substituted aryl group and optionally substituted heteroaryl group, by reacting a compound of the formula II where R 2 and R 3 each have the same meaning as in formula I, with a compound of the formula III X-R 1 -X 1 where X and R 1 each have the same meaning as in formula I, and X 1 is a halogen atom, and with a compound of the formula IV where R 4 and R 5 each have the same meaning as in formula I, in the presence of a base of the formula V where R 6, R 7 and R 9 may be identical or different and, independently of one another, are hydrogen or an optionally substituted, saturated or unsaturated hydrocarbon radical, where R 7 and R 9 may together also form an optionally substituted, saturated or unsaturated hydrocarbon bridge, and R 8 is hydrogen or an optionally substituted, saturated or unsaturated hydrocarbon radical or the radical -NR 10 R 11, where the radicals R 10 and R 11 may be identical or different and are hydrogen or an optionally substituted, saturated or unsaturated hydrocarbon radical, where the radicals R 6 and R 8 may together also form an optionally substituted hydrocarbon bridge, and in the presence of at least one activating reagent selected from the group of activating reagents 1,1'-carbonyldiimidazole, 1,1'-thiocarbonyldiimidazole and thionyldiimidazole. X is a halogen atom, R 1 is selected from the group consisting of optionally substituted alkylene group, optionally substituted alkenylene group and the group -R-Z-R-, where each R, independently of the others, is a covalent bond, an optionally substituted alkylene group or an optionally substituted alkenylene group, where both R groups may not be a covalent bond at the same time, and Z is an optionally substituted cycloalkyl group, an optionally substituted heterocyclyl group, an optionally substituted aryl group or an optionally substituted heteroaryl group, R 2 and R 3, independently of one another, are selected from the group consisting of hydrogen, optionally substituted alkyl group and optionally substituted cycloalkyl group, and R 4 and R 5, independently of one another, are selected from the group consisting of hydrogen, halogen atom, optionally substituted alkyl group, optionally substituted alkenyl group, optionally substituted cycloalkyl group, optionally substituted heterocyclyl group, optionally substituted aryl group and optionally substituted heteroaryl group, X and R 1 each have the same meaning as in formula I, and X 1 is a halogen atom, R 6, R 7 and R 9 may be identical or different and, independently of one another, are hydrogen or an optionally substituted, saturated or unsaturated hydrocarbon radical, where R 7 and R 9 may together also form an optionally substituted, saturated or unsaturated hydrocarbon bridge, and R 8 is hydrogen or an optionally substituted, saturated or unsaturated hydrocarbon radical or the radical -NR 10 R 11, where the radicals R 10 and R 11 may be identical or different and are hydrogen or an optionally substituted, saturated or unsaturated hydrocarbon radical, where the radicals R 6 and R 8 may together also form an optionally substituted hydrocarbon bridge,
