Procedure

2-(6-Chloro-benzothiazol-2-ylamino)-1-(2-methoxy-ethyl)-1H-benzoimidazole-5-carboxylic acid dimethylcarbamoylmethyl-amide (24 mg) was prepared by following General Procedure F starting from 2-(6-chloro-benzothiazol-2-ylamino)-1-(2-methoxy-ethyl)-1H-benzoimidazole-5-carboxylic acid (80 mg), 2-amino-N,N-dimethyl-acetamide (40 mg), HBTU (95 mg), and DIEA (70 uL) in DMF (1 mL). LC/MS: m/z 486.5. 1H NMR (DMSO-d6, 400 MHz): δ 8.57-8.56 (m, 1H), 8.11 (s, 1H), 8.01-8.00 (d, 1H), 7.84-7.82 (m, 1H), 7.63-7.61 (d, 1H), 7.57-7.54 (d, 1H), 7.46-7.44 (m, 1H), 4.43-4.40 (t, 2H), 4.14-4.13 (d, 2H), 3.75-3.72 (t, 2H), 3.24 (s, 3H), 3.04 (s, 3H), 2.87 (s, 3H), —NH proton signal was not observed.
