Procedure

1-Methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzimidazole-5-carboxylic acid (2-oxo-2-pyrrolidin-1-yl-ethyl)amide (46 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), pyrrolidine (0.14 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 520. 1H NMR (DMSO-d6, 400 MHz): δ 8.32 (t, 1H), 7.82 (s, 1H), 7.61 (m, 2H), 7.52 (d, 1H), 7.28 (m, 1H), 7.17 (m, 1H), 7.09 (m, 1H), 4.02 (d, 2H), 3.57 (s, 3H), 3.49 (t, 2H), 3.34 (m 2H), 1.91 (p, 2H), and 1.79 (p, 2H).
