Versuchsvorschrift

4-[(1-tert-Butoxycarbonyl-4-piperidinyl)oxy]benzonitrile (D21) (6.83 g) was dissolved in DCM (30 ml) and TFA (30 ml) was added. The reaction was stirred at rt for 1 h and then evaporated to give the title compound (D22) as a yellow oil (7.15 g—TFA salt plus 1.3 equivalents of TFA).
