実験手順

To a solution of 4-iodo-2-(trifluoromethoxy)aniline (0.606 g, 2.00 mmol) in 8 mL DMF was added dimethylphosphine oxide (0.171 g, 2.20 mmol), palladium acetate (22.4 mg, 0.0100 mmol), XANTPHOS (69.4 mg, 0.120 mmol), and potassium phosphate (0.467 g, 2.20 mmol). The mixture was purged with nitrogen, and subjected to microwaves at 150° C. for 20 minutes. The reaction mixture was concentrated and purified by silica gel chromatography (0-20% 7N ammonia in methanol:dichloromethane) and acidified with HCl in methanol to afford the desired product as its hydrochloride salt (0.573 g, 98% yield).
