Reaction Steps

2-(5,6-Dimethoxy-benzoimidazol-1-yl)-4-phenyl-thiazole-5-carboxylic acid cyclopropylamide was prepared from 2-(5,6-Dimethoxy-benzoimidazol-1-yl)-4-phenyl-thiazole-5-carboxylic acid ethyl ester (24 mg, 0.06 mmol) and cyclopropylamine in methanol (4 molar) as described above in the general amide formation procedure. Product was isolated by preparative HPLC: 10 mg, 40%. 1H-NMR (DMSO-D6) 8.8 (s, 1H); 8.54 (t, 1H); 7.80-7.87 (m, 2H), 7.41-7.55 (m, 3H); 7.38 (s, 1H); 3.90 (s, 3H); 3.86 (s, 3H); 3.25 (q, 2H); 1.08 (t, 3H). MS M/z 421 (M+1).
