実験手順

A mixture of 2-(4-bromo-3-fluorophenyl)-6-[(R)-1-(tetrahydrofuran-2-yl)methoxy]-2H-isoquinolin-1-one (75 mg), palladium(II) acetate (3 mg), BINAP (14 mg), cesium carbonate (82 mg) and pyrrolidin-3-yl-carbamic acid tert-butyl ester (48 mg) in degassed toluene (2 mL) was stirred for 18 h at 100° C. The mixture was diluted with ethyl acetate, filtered and the filtrate was concentrated. The residue was purified by preparative HPLC. In this way the product was obtained with molecular weight 523.61 (C29H34FN3O5); MS (ESI): 524 (M+H+).
