Procedure

This compound is prepared by an analogous method to (1R/S,3R)-3-((R/S)-(2-cyclohexyl-2-hydroxy-2-phenyl-acetoxy)-1-methyl-1-(pyrazin-2-ylcarbamoylmethyl)-pyrrolidinium bromide (Example 1) by replacing (1R/S,3R)-3-hydroxy-1-methyl-1-(pyrazin-2-yl-carbamoylmethyl)-pyrrolidinium bromide (Intermediate B) with (R)-3-hydroxy-1-methyl-1-(pyridazin-3-ylcarbamoylmethyl)-pyrrolidinium bromide (Intermediate F).
