Procedure

Following the procedure described in Example 17, Step 2, {3-methyl-5-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-isoxazol-4-yl}-carbamic acid 1-(2-chloro-phenyl)-ethyl ester, 3-(4-bromo-phenyl)-propionic acid ethyl ester, and bis(triphenylphosphine)palladium(II) dichloride were reacted to provide 3-(4′-{4-[1-(2-chloro-phenyl)-ethoxycarbonylamino]-3-methyl-isoxazol-5-yl}-biphenyl-4-yl)-propionic acid ethyl ester, which was hydrolyzed to the acid as described in Example 17, Step 3.
