Reaction Conditions

Reaction Steps

Under argon gas atmosphere, a mixture of methyl 4-bromo-1-(2,4,6-trifluorophenyl)isoquinoline-7-carboxylate (150 mg), ethylboronic acid (84 mg), tetrakis(triphenylphosphine)palladium (44 mg), tripotassium phosphate (241 mg), toluene (5 mL), and water (0.3 mL) was heated under stirring in an oil bath at 100° C. for one day. The reaction mixture was returned to room temperature, and diluted with water and ethyl acetate, and then the insoluble matter was separated by filtration. The filtrate was extracted with ethyl acetate, and the organic layer was concentrated under reduced pressure. The resulting residue was purified under silica gel column chromatography (hexane/ethyl acetate) to obtain methyl 4-ethyl-1-(2,4,6-trifluorophenyl)isoquinoline-7-carboxylate (71 mg).
