Reaction Steps

This compound is prepared using an method analogous to (R)-3-[2-hydroxy-2-(4-methoxy-phenyl)-2-phenyl-acetoxy]-1-(isoxazol-3-ylcarbamoylmethyl)-1-azonia-bicyclo[2.2.2]-octane bromide (Example 22) by replacing hydroxy-(4-methoxy-phenyl)-phenyl-acetic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl) ester (Intermediate O) with hydroxy-phenyl-o-tolyl-acetic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl) ester (Intermediate P).
