In a similar manner as described for Example 26, 4-bromo-2-(5,6-dimethoxy-benzoimidazol-1-yl)-thiazole-5-carboxylic acid methyl ester (40 mg, 0.1 mmol) and 3,4-methylenedioxybenzeneboronic acid (24.9 mg, 0.15 mmol) gave 4-Benzo[1,3]dioxol-5-yl-2-(5,6-dimethoxy-benzoimidazol-1-yl)-thiazole-5-carboxylic acid (10.5 mg, 25%) as a white solid. MS m/z 426 (M+1).
