Procedure

1-Methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzimidazole-5-carboxylic acid diethylcarbamoylmethyl-amide (48 mg) was prepared by following General Procedure F using {[1-methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzimidazole-5-carbonyl]-amino}-acetic acid (47 mg), diethylamine (0.2 ml), HBTU (38 mg), and DIEA (0.1 ml), with a minor modification of General Procedure F where DIEA was slowly added to the reaction mixture at last while stirring at 0° C. LC/MS: m/z 522. 1H NMR (DMSO-d6, 400 MHz): δ 8.45 (t, 1H), 8.08 (s, 1H), 7.90 (m, 2H), 7.78 (br, 1H), 7.66 (br, 1H), 7.48 (d, 1H), 7.34 (d, 1H), 4.13 (d, 2H), 3.66 (s, 3H), 3.38-3.28 (m, 4H), and 1.05 (t, 6H).
