Reaction Steps

To a solution of 4-[3-[7-(3-bromo-5-dimethylcarbamoyl-phenyl)-hept-6-ynyl]-2-(2-carboxy-ethyl)-phenoxy]-butyric acid (80 mg, 0.14 mmol) in EtOH (4 mL)/H2O (1 mL) were added 4-hydroxyphenylboronic acid (38 mg, 0.28 mmol), potassium carbonate (77 mg, 0.56 mmol) and Pd(PPh3)4 (3 mg, 0.0028 mmol). The mixture was heated at 78° C. for 5 h and then cooled to room temperature. The reaction mixture was filtered using a syringe filter 0.45 μm and the filtrate was concentrated under reduced pressure. The crude oil was then purified by preparative HPLC using acetonitrile/water gradient.
