Reaction Steps
A solution of 660 mg (1.19 mmol) of 4-cyano-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-2-carboxylic acid [2-cyclohex-1-enyl-4-(2-dimethylsulfamoyl-ethyl)-phenyl]-amide (as prepared in the previous step) in CH2Cl2 (30 mL) was treated with EtOH (600 μL) and TFA (3 mL) and stirred at RT for 24 h. MeOH (20 mL) was added, and the solvents were evaporated in vacuo. The solid was triturated with acetonitrile to afford 342 mg (67%) of the title compound as a white solid: 1H-NMR (CD3CN; 400 MHz): δ 8.20-8.09 (m, 1H), 7.92 (s, 1H), 7.24-7.16 (m, 1H), 7.13 (s, 1H), 5.84-5.75 (m, 1H), 3.30-3.19 (m, 4H), 3.08-2.96 (m, 2H), 2.82 (s, 6H), 2.29-2.17 (m, 4H), 1.85-1.68 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C21H25N5O3S, 428.2 (M+H). found 428.1.
