실험 절차

A solution of methyl 5-bromo-6-cyclohexyl-4H-thieno[3,2-b]pyrrole-2-carboxylate (7 g, 20 mmol), 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenylamine (4.8 g, 22 mmol), sodium hydrogen carbonate (6.7 g, 80 mmol) and tetrakis(triphenylphosphine)palladium (230 mg, 0.2 mmol) in water (20 ml) and ethylene glycol dimethyl ether (50 ml) was stirred with heating under reflux for 4 hr. The reaction mixture was cooled to room temperature and ethyl acetate (200 ml) was added. The mixture was washed successively with water (100 ml), saturated aqueous sodium hydrogen carbonate solution (100 ml) and saturated brine (100 ml), and dried over magnesium sulfate. Filtration and concentration under reduced pressure gave a crude product of methyl 5-(2-aminophenyl)-6-cyclohexyl-4H-thieno[3,2-b]pyrrole-2-carboxylate. The obtained compound was used for Step 10 without purification.
