Versuchsvorschrift

To a solution of 4-(3-hydroxymethyl-[1,2,4]triazol-1-yl)-piperidine-1-carboxylic acid tert-butyl ester (from Step 2 above, 0.181 g, 0.641 mmol) and triethylamine (0.134 mL, 0.961 mmol) in dichloromethane (5 mL) at 0° C. was added methanesulfonylchloride (0.055 mL, 0.705 mmol). The resulting solution was stirred at room temperature for 1 hour. The solvent was removed in vacuo to yield the desired product as a light yellow oil that was used without further purification.
