Versuchsvorschrift
7.6 g of methyl 2-benzyloxy-5-[2-[1,1-dimethyl-3-[1,2,4]triazol-1-yl-propylamino]-1-hydroxy-ethyl]-benzoate are reduced in an ethanolic calcium chloride solution with sodium borohydride as described for Example 1c. The product is obtained as a colourless oil after purification by column chromatography (CHCl3/MeOH/NH3=90/10/0.5). Yield: 6 g (84%).
