Versuchsvorschrift

This compound is prepared by an analogous method to (1R/S,3R)-3-Hydroxy-1-(isoxazol-3-ylcarbamoylmethyl)-1-methyl-piperidinium bromide (Intermediate C) by replacing (R)-1-methyl-piperidin-3-ol (step C3) with 1-methyl-piperidin-4-ol and by replacing 2-bromo-N-isoxazol-3-yl-acetamide (Intermediate A) with 2-phenoxy-ethylbromide.
