Versuchsvorschrift

A solution of (RS)-2-(5-phenyl-[1,3,4]oxadiazol-2-ylmethyl)-piperidine-1-carboxylic acid tert butyl ester (0.175 g) in dichloromethane (4 ml) was cooled (ice bath) and treated with trifluoroacetic acid (1 ml). The mixture was stirred for 1 h, added to saturated potassium carbonate and the product extracted into dichloromethane. The organic phase was dried (MgSO4) and solvent removed at reduced pressure to give the title compound (0.115 g)
