Reaction Steps
1-Isopropyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzoimidazole-5-carboxylic acid methylamide (44.0 mg) was prepared by following General Procedure F starting from 1-isopropyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzo-imidazole-5-carboxylic acid (100.0 mg), methylamine (2.0 M solution in THF, 0.5 mL), HBTU (130.0 mg) and DIEA (0.1 mL) in DMF (1.0 mL). LCMS: m/z 451; and 1H NMR (DMSO-d6, 400 MHz): δ 8.40 (1H, m), 8.10 (1H, m), 7.92 (1H, m), 7.75-7.68 (2H, m), 7.37-7.35 (1H, m), 5.17-5.12 (1H, m), 2.82-2.80 (3H, s), 1.58-1.57 (6H, d), 2 —NH proton signals were not observed.
