  • Patent number: 8846954
    Abstract: A method for the production of crystalline glycopyrronium bromide, comprises the reaction of glycopyrronium base with methyl bromide in a solvent, in which the solvent is selected such that the diastereoisomeric ratio of the product favors the R,S and S,R diastereoisomers over the R,R, and S,S diastereoisomers, and separating the desired diastereoisomers by one or more controlled crystallization steps. This method gives a product having a particle size of narrow distribution.
