Versuchsvorschrift

75 mg of 1-{2-[5-(3-Amino-phenyl)-2H-[1,2,4]triazol-3-yl]-piperidin-1-yl}-2-phenoxy-ethanone were dissolved in MDF and 40 ul DIPEA added. 34 mg of 3-Bromo-propionyl chloride were added at 0° C. and the reaction warmed up to rt and stirred for another 30 min. The reaction mixture was heated to 120° C. using microwave heating and the product was isolated via preparative HPLC.
