Procedure

To a flask was added 5-[1-[4-(2,4-bis-trifluoromethyl-benzyloxy)-3-methoxy-phenyl]-methylidene]-2-piperazin-1-yl-thiazol-4-one (50 mg, 92 μmol) (from Example 23) chloroform (5 mL), methyl sulfonyl chloride (3 equiv, 32 μL) and TEA (3 equiv, 40 μL). The reaction was stirred at 60° C. under N2. The reaction solution was diluted with DCM (70 mL), washed with aq NH4Cl, dried over Na2SO4, filtered, and concentrated in vacuo. The crude material was chromatographed (SiO2, DCM/MeOH 100:0 to 90:10) to provide the title compound as a white solid (30 mg, 52%). 1H NMR (DMSO-d6) δ 7.99 (2H, s), 7.94 (1H, s), 7.62 (1H, s), 7.18 (1H, s), 7.13 (1H, dd, J1=2.0 Hz, J2=8.4 Hz), 7.01 (1H, d, J=8.4 Hz), 5.37 (2H, s), 4.06 (2H, m), 3.88 (3H, s), 3.74 (2H, m), 3.31-3.36 (4H, m), 2.85 (3H, s); MS (ESI) 624 (MH+).
