Procedure

34 mg (0.10 mmol) (S)—N-{1-(4-[1-(4-Hydroxyphenyl)-piperidin-4-yl]-phenyl}-ethyl)-acetamide (compound 1.48), 15 mg (0.15 mmol) tetrahydro-4H-pyran-4-ol and 39 mg (0.15 mmol) triphenylphosphine on solid support are suspended in 2 mL anhydrous THF at 0° C. 35 mg (0.15 mmol) di-tert-Butyl azodicarboxylate are added and the mixture is allowed to warm to rt. Stirring is continued over night followed by addition of 0.5 equivalents of triphenylphosphine on solid support and 0.5 equivalents of di-tert-butyl azodicarboxylate. After stirring for 2 h at rt, the mixture is filtered over basic aluminum oxide and washed with DMF/MeOH (9:1). After evaporation the residue is purified using reversed phase HPLC (water/MeOH, 0.1% TFA) to yield the desired product.
