Procedure

To a mixture of intermediate D70 (1 g, 3 mmol) in toluene (25 ml) under a nitrogen atmosphere were added methylboronic acid (0.897 g, 15 mmol), dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine; X-Phos (0.286 g, 0.6 mmol), palladium(II)acetate (0.067 g, 0.3 mmol) and K2CO3 (1.243 g, 9 mmol). The reaction mixture was heated at 100° C. for two days. After cooling, the mixture was diluted with EtOAc and washed with water. The organic layer was separated and concentrated in vacuo. The residue was purified by column chromatography (silica gel; DCM/EtOAc from 100/0 to 0/100 as eluent). The desired fractions were collected and concentrated in vacuo to yield intermediate D98 (0.365 g, 55%).
