Procedure

The title compound was made in a similar way as that of the intermediate B2 using 4-bromo-3-(hydroxymethyl)-1H-isochromen-1-one (Intermediate A1, 0.5 g, 1.960 mmol), 3-fluorophenylboronic acid (0.4 g, 2.86 mmol), Pd(PPh3)4 (0.136 g, 0.118 mmol) and Cs2CO3 (0.96 g, 2.94 mmol) to afford the title compound (0.21 g, 40%).
