実験手順

1-Bromo-4-hydroxy-7-phenylsulfanyl-isoquinoline-3-carboxylic acid methyl ester (0.2 g), tetrakis(triphenylphosphine)palladium (60 mg), methyl boroxine (65 mg), and potassium carbonate in 1,4-dioxane (4 ml) were heated in a microwave reactor (sealed tube) for 10 min at 140° C. After cooling reaction mixture was concentrated and partitioned between 1N hydrochloric acid and ethyl acetate. Organic layer dried over magnesium sulfate and filtered. Filtrate concentrated and separated by silica gel chromatography (eluting with 2% ethyl acetate in methylene chloride) to give the title compound (47 mg). MS-(+)-ion M+1=326.1.
