Procedure

To a solution of 4-cyano-1H-imidazole-2-carboxylic acid [2-(4,4-dimethyl-cyclohex-1-enyl)-4-(1-methyl-1-thiomorpholin-4-yl-ethyl)-phenyl]-amide (as prepared in Example 14, step (e), 30.0 mg, 0.0647 mmol) in 0.5 mL of DCM at RT was added titanium (IV) isopropoxide (19 μL, 0.065 mmol). The mixture was cooled to 0° C. and H2O2 (13 μL, 0.13 mmol, 30 wt % in H2O) was added. After stirring at 0° C. for 4 h, the mixture was treated with EtOAc (50 mL) and washed with H2O (2×10 mL) and brine (10 mL). The organic layer was dried over Na2SO4 and concentrated in vacuo, the residue was purified by silica gel chromatography (1-4% MeOH/DCM) to afford the title compound (30 mg, 95%) as a colorless oil. 1H-NMR (CDCl3; 400 MHz): δ 13.06 (s, 1H), 9.63 (s, 1H), 8.34 (d, 1H, J=8.6 Hz), 7.71 (s, 1H), 7.51 (dd, 1H, J=8.6, 2.0 Hz), 7.27 (d, 1H, J=2.0 Hz), 5.78 (m, 1H), 3.17 (m, 2H), 2.84-3.08 (m, 4H), 2.71 (m, 2H), 2.28 (m, 2H), 2.11 (m, 2H), 1.60 (t, 2H, J=6.3 Hz), 1.40 (s, 6H), 1.11 (s, 6H). Mass spectrum (ESI-neg, m/z): Calcd. for C26H33N5O2S, 478.2 (M−H). found 478.3.
