Procedure

1-Ethyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzo-imidazole-5-carboxylic acid ethylamide (53.0 mg) was prepared by following General Procedure F starting from 1-methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzo-imidazole-5-carboxylic acid (100.0 mg), ethylamine (2.0 M solution in THF, 1 mL), DPPA (85.0 mg), and DIEA (0.1 mL) in DMF (1.0 mL). LCMS: m/z 451; and 1H NMR (CD3OD, 400 MHz): δ 7.95 (1H, d), 7.75-7.73 (2H, m), 7.65-7.64 (1H, d), 7.42-7.40 (1H, m), 7.26-7.24 (1H, m), 4.27-4.25 (2H, q), 3.47-3.42 (2H, q), 1.42-1.39 (3H, t), 1.27-1.24 (3H, t) 2 —NH proton signals were not observed.
