Methyl iodide (3.48 g) was added dropwise to a solution of 8-(2-chlorobenzyloxy)-3-dimethylaminomethyl-2-methylimidazo[1,2-a]pyridine (7.8 g) in acetone (100 ml) at room temperature and the mixture was stirred for 24 hours. The resulting precipitate was collected by filtration, washed with acetone, and dried in a desiccator to give 8-(2-chlorobenzyloxy)-3-trimethylammoniomethyl-2-methylimidazo[1,2-a]pyridine iodide (11.35 g).
