Reaction Steps
This compound is prepared by an analogous method to (1R/S,2R)-2-((R/S)-(2-Cyclohexyl-2-hydroxy-2-phenyl-acetoxymethyl)-1-(isoxazol-3-yl carbamoylmethyl)-1-methyl-pyrrolidinium bromide (Example 1) by replacing (1R/S,2R)-2-hydroxymethyl-1-(isoxazol-3-ylcarbamoyl-methyl)-1-methyl-pyrrolidinium bromide (Intermediate B) with 4-hydroxy-1-(isoxazol-3-ylcarbamoylmethyl)-1-methyl-piperidinium bromide (Intermediate I).
