3-Benzyloxy-phenylboronic acid → HCID 66931060, compound

Participants

Reaction Steps

2-(3-Benzyloxy-biphenyl-3-yl)-acetic acid methyl ester (32) was synthesized following the procedure described for the preparation of 29 using 3-bromo-phenyl acetic acid methyl ester (31) (0.31 g, 1.35 mmol), 3-benzyloxy-phenyl boronic acid (0.45 g, 2 mmol), barium hydroxide (0.5 g, 3 mmol) and Pd(PPh3)4 (0.15 g, 0.13 mmol), in DME (10 mL)/water (4 mL). Purification by flash column chromatography on silica gel gave pure compound 32 (0.22 g, 49% yield) as a white solid (m p 50-52° C.).
