Reaction Conditions

Reaction Steps

In a nitrogen atmosphere, a mixture of dimethyl 5-trifluoromethanesulfonyloxyisophthalate (1.37 g, 4.00 mmol), pyrrolidine (0.50 mL, 6.00 mmol), tris(dibenzylideneacetone)dipalladium(0) (37 mg, 0.040 mmol), 2-(di-tert-butylphosphino)biphenyl (24 mg, 0.080 mmol), potassium phosphate (1.19 g, 5.60 mmol) and 1,2-dimethoxyethane (12 mL) was stirred at 80° C. for 12 hours. After left cooled, the reaction mixture was diluted with ethyl acetate, filtered through Celite, and the filtrate was concentrated under reduced pressure. The residue was purified through silica gel column chromatography to obtain the title compound as a yellow solid.
