反応手順

The title compound was made in a similar way as that of the intermediate B1, using 4-bromo-3-(1-hydroxyethyl)-1H-isochromen-1-one (Intermediate A2, 0.36 g, 1.35 mmol), 4-(2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)ethyl)-morpholine (0.45 g, 1.35 mmol), Pd(PPh3)4 (0.078 g, 0.068 mmol) and Cs2CO3 (0.53 g, 1.6 mmol). The crude was filtered, diluted with 1M HClaqueous (3 ml) and purified via reverse phase chromatography with a Biotage C18 SNAP 120 g column (Phase A, water 95%, ACN 4.9%, formic acid 0.1%); Phase B ACN 99.9%, formic acid 0.1%) to afford the title compound (0.179 g, 33%).
