Procedure

To a mixture of D70 (0.6 g, 1.8 mmol) in toluene (15 ml) under a nitrogen atmosphere were added methylboronic acid (0.538 g, 9 mmol), dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine; S-Phos (0.171 g, 0.36 mmol), palladium(II)acetate (0.04 g, 0.18 mmol) and K2CO3 (0.745 g, 5.396 mmol). The reaction mixture was heated at 100° C. overnight. 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 20/80 as eluent). The desired fractions were collected and concentrated in vacuo to yield intermediate D71 (0.312 g, 78%) as a cream solid.
