Versuchsvorschrift

1-Methyl-2-(6-trifluoromethyl-benzothiazol-2-ylamino)-1H-benzoimidazole-5-carboxylic acid [2-((S)-3-methoxy-piperidin-1-yl)-2-oxo-ethyl]amide (77 mg) was prepared by following General Procedure F starting from {[1-methyl-2-(6-trifluoromethyl-benzothiazol-2-ylamino)-1H-benzoimidazole-5-carbonyl]-amino}-acetic acid (100 mg), (S)-3-methoxy-piperidine hydrochloride (37 mg), HBTU (101 mg), and DIEA (58 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 546.7. 1H NMR (DMSO-d6, 400 MHz): δ 12.51 (bs, 1H), 8.57-8.47 (m, 1H), 8.26 (s, 1H), 8.14 (s, 1H), 7.89-7.66 (m, 3H), 7.54 (d, 1H), 4.33-4.15 (m, 1H), 4.15-4.00 (m, 1H), 3.81-3.56 (m, 4H), 3.55-3.44 (m, 1H), 3.43-3.18 (m, 6H), 2.01-1.21 (m, 4H).
