Reaction Steps

In a reaction vessel charged with 4 mL of toluene and 1 mL of water, was added 45 mg (0.072 mmol) of 4-[3-[6-(5-bromo-4′-dimethylamino-biphenyl-3-yloxy)-hexyl]-2-(2-carboxy-ethyl)-phenoxy]-butyric acid, 3-fluorophenylboronic acid (20 mg, 0.144 mmol), and potassium phosphate (35.9 mg, 0.144 mmol). This mixture was put under an atmosphere of nitrogen and 4.16 mg of tetrakis(triphenylphosphine)palladium(0) was added. This mixture was stirred and was heated overnight at 90° C. At this time, analysis of an aliquot by LC-MS, indicated the formation of the desired product. To the reaction mixture was added 2N HCl to effect pH=˜6. The aqueous phase was thrice extracted with ethyl acetate. The combined organic phases were dried with MgSO4, filtered and washed with ethyl acetate. The filtrate was concentrated in vacuo to provide a solid which was purified by preparative HPLC to provide 46 mg of product. Example 57 was characterized by low resolution mass spectrometry where signals corresponding to the following were observed: ES(+)=598+Na, ES(−)=597. Example 57 was also characterized by high resolution mass spectrometry where signals corresponding to the following were observed: m/e calculated for C37H39FO6 598.273068; found compatible with (M+Na)1+=621.2624.
