(S)-3-(4-Bromo-phenyl)-2-{5-chloro-2-[(naphthalen-1-ylmethyl)-amino]-benzoylamino}-propionic acid methyl ester (150 mg, 0.36 mmol), Pd (PPh3)4 (84 mg, 0.072 mmol), and 4-phenoxyphenylboronic acid (233 mg, 1.09 mmol) were dissolved in 5 mL of toluene, a 1M Na2CO3 solution (0.9 mL, 0.91 mmol) added and the mixture heated at 80° C. for 12 h. The reaction mixture was diluted with 5 mL of CH2Cl2 and filtered, all volatiles are removed under vaccum and the ester product was hydrolyzed according to Procedure C, and purified over silica gel (ethyl acetate:hexanes) to give the title compound(118 mg) as a white solid.
