Procedure

1-Methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzoimidazole-5-carboxylic acid [2-(4-hydroxy-piperidin-1-yl)-2-oxo-ethyl]amide (65 mg) was prepared by following General Procedure F starting from {[1-methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzoimidazole-5-carbonyl]-amino}-acetic acid (75 mg), 4-hydroxypiperidine (18 mg), HBTU (73 mg), and DIEA (42 uL), with a modification of General Procedure F where DIEA was slowly added to the reaction mixture as the last reagent. LC/MS: m/z 549.7. 1H NMR (DMSO-d6, 400 MHz): δ 8.41 (t, 1H), 8.11 (s, 1H), 7.94 (s, 1H), 7.80 (d, 1H), 7.65 (bs, 1H), 7.51 (d, 1H), 7.37 (d, 1H), 4.15 (d, 2H), 3.98-3.89 (m, 2H), 3.78-3.69 (m, 2H), 3.68 (s, 3H), 3.20 (t, 1H), 3.04 (t, 1H), 1.84-1.67 (m, 2H), 1.45-1.20 (m, 2H), —NH proton signal was not observed.
