Procedure

To a mixture of 4-cyano-1H-imidazole-2-carboxylic acid [4-(1-acetyl-4-hydroxy-piperidin-4-yl)-2-(4,4-dimethyl-cyclohex-1-enyl)-phenyl]-amide (as prepared in Example 35, 40.0 mg, 0.0867 mmol) and NaN3 (56.3 mg, 0.0867 mmol) in 2 mL of DCM at 0° C. under Ar was added TFA (100 μL, 1.30 mmol). The resulting mixture was stirred at 0° C. for 0.5 h, at RT for 2 d under Ar. Treated with 20 mL of EtOAc, the mixture was washed with saturated NaHCO3 aqueous solution (10 mL), brine (5 mL) and dried (Na2SO4). Removal of the solvent under reduced pressure followed by flash chromatography of the residue on silica gel (1-3% MeOH/DCM) gave 40.0 mg (95%) of the title compound as a white solid. Mass spectrum (ESI, m/z): Calcd. for C26H30N8O2, 487.3 (M+H). found 487.0.
