실험 절차

A solution of 177 mg (0.326 mmol) of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid [2-cyclohex-1-enyl-4-(2-methylsulfamoyl-ethyl)-phenyl]-amide (as prepared in the previous step) in CH2Cl2 (10 mL) was treated with MeOH (300 μL) and TFA (3 mL) at RT for 45 min. MeOH (10 mL) was added, and solvents were evaporated in vacuo. The solid residue was triturated with a minimum amount of acetonitrile with sonication, but further purification was needed. Silica gel chromatography of the solid with 50% EtOAc-hexane also afforded impure material. The solid was purified by RP-HPLC (C18) with 40-100% CH3CN in 0.1% TFA/H2O over 30 min to afford 14.9 mg (11%) of the title compound as a white solid: 1H-NMR (CD3CN; 400 MHz): δ 9.38 (s, 1H), 8.27-8.20 (m, 1H), 7.93 (s, 1H), 7.27-7.20 (m, 1H), 7.18-7.14 (m, 1H), 5.89-5.82 (m, 1H), 5.09-5.01 (m, 1H), 3.36-3.26 (m, 2H), 3.08-3.00 (m, 2H), 2.70 (d, 3H, J=5.2 Hz), 2.32-2.25 (m, 4H), 1.90-1.74 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C20H23N5O3S, 414.1 (M+H). found 414.1.
