Versuchsvorschrift

A solution of 2-bromo-6-(2-ethyl-1-(1H-imidazol-1-yl)butyl)benzo[d]thiazole (93 mg, 0.255 mmol), (4-(methoxycarbonyl)phenyl)boronic acid (50.6 mg, 0.281 mmol), tetrakis(triphenylphosphine)palladium (29.5 mg, 0.0255 mmol), potassium carbonate (106 mg, 0.765 mmol), DME (5 mL) and water (0.8 mL) was degassed, filled with N2, and heated to 80° C. for 6 h. The reaction mixture was evaporated. The crude product was purified by column chromatography using 5 MeOH in DCM as eluent to afford to methyl 4-(6-(2-ethyl-1-(1H-imidazol-1-yl)butyl)benzo[d]thiazol-1-yl)benzoate as white solid. MS (ES+): m/z 420.28 (MH+).
