Versuchsvorschrift
A solution of 0.615 g of the compound obtained in EXAMPLE 93 in 2 ml of DCM is cooled to 0° C. and 2 ml of TFA are added. The mixture is stirred for 30 minutes and evaporated under vacuum and the residue is then taken up with DCM and evaporated under vacuum again to give the expected product, which is used as such in the next step.
