Procedure: A mixture of (3-Phenoxy-phenyl)-acetic acid (10.00 g, 0.0438 mol), 2-amino-pentanoic acid methyl ester (7.34 g, 0.0438 mol.), HBOT (6.20 g, 0.046 mol), EDC. HCl (12.59 g, 0.067 mol) and a trimethylamine (30.45 ml, 0.22 mol) in methylene chloride (150 ml) was stirred at room temperature overnight. The mixture was quenched with water and extracted with methylene chloride. The organic layer was washed with 1N HCl, then brine, dried over sodium sulfate and the solvent was removed at reduced pressure to provide 13.99 g of (3-phenoxy-phenyl)-acetic acid methyl ester as a thick oil, LC-MS M+1=342. The mixture was quenched with water extracted with methylene chloride The organic layer was washed with 1N HCl brine, dried over sodium sulfate the solvent was removed at reduced pressure
