(+-)-Cyclohexylphenylglycolic acid → (R)-3-(2-Cyclohexyl-2-hydroxy-2-phenyl-acetoxy)-1-(pyrimidin-4-ylcarbamoylmethyl)-1-azonia-bicyclo[2.2.2]octane bromide

Participants

Reaction Steps

This compound is prepared analogously to (R)-3-(2-Cyclopentyl-2-hydroxy-2-phenyl-acetoxy)-1-(pyrazin-2-ylcarbamoylmethyl)-1-azonia-bicyclo[2.2.2]octane bromide (Example 15) by replacing (R)-3-Hydroxy-1-(pyrazin-2-ylcarbamoylmethyl)-1-azonia-bicyclo-[2.2.2]octane bromide (Intermediate H) with (R)-3-Hydroxy-1-(pyrimidin-4-ylcarbamoyl-methyl)-1-azonia-bicyclo[2.2.2]octane bromide (Intermediate Q) and by replacing cyclopentyl-hydroxy-phenyl-acetic acid with cyclohexyl-hydroxy-phenyl-acetic acid, yielding the titled compound as a diastereomeric mixture. (M+479.5).
