Reaction Conditions

Reaction Steps

Under argon gas atmosphere, a mixture of methyl 4-bromo-1-(2,4,6-trifluorophenyl)isoquinoline-7-carboxylate (160 mg), trimethylboroxin (117 mg), tetrakis(triphenylphosphine)palladium (23 mg), 2M aqueous sodium carbonate solution (1 mL), and 1,4-dioxane (5 mL) was heated under stirring in an oil bath at 100° C. for 4 hours. The reaction mixture was returned to room temperature and diluted with ethyl acetate, and then the insoluble materials were separated by filtration through Celite. The filtrate was extracted with ethyl acetate. The organic layer was concentrated under reduced pressure, and the resulting residue was purified under silica gel column chromatography (hexane/ethyl acetate) to obtain 4-methyl-1-(2,4,6-trifluorophenyl)isoquinoline-7-carboxylic acid (95 mg).
