実験手順

To N-(1-bromoisoquinolin-3-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (508 mg, 1.14 mmol) in 1,2-dimethoxyethane (11 mL) was added 3-(tert-butoxycarbonyl)phenylboronic acid (328 mg, 1.48 mmol), tetrakis(triphenylphosphine)palladium (0) (131 mg, 0.114 mmol), and 2 M Na2CO3 (1.71 mL, 3.41 mmol). The mixture was heated at 80° C. overnight before it was diluted with ethyl acetate (10 mL) and washed with water (20 mL). The organics were dried over Na2SO4 and evaporated. The resulting crude material was purified by silica gel chromatography eluting with 0-10% ethyl acetate in hexanes to yield tert-butyl 3-(3-(1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)isoquinolin-1-yl)benzoate (603 mg, 97%). ESI-MS m/z calc. 544.6. found 545.3 (M+1)+. Retention time 2.76 minutes.
