A solution of 60.1 mg (0.23 mmol) of the compound from example 1g, 68.9 mg (0.23 mol) of 4-bromo-1-benzyloxycarbonylpiperidine, 97 μl (0.69 mmol) of triethylamine in 1 ml of absolute THF was treated in a microwave at 180° C. for 2 h. The reaction solution was then mixed with 2 ml of EA/water (1:1), and the EA phase was separated off and dried over Na2SO4. Filtering, stripping off the solvent and purifying the remaining residue by chromatography on RP silica gel with CH3CN/water/0.1% TFA as mobile phase afforded 33 mg of the title compound as bistrifluoroacetate.
