Procedure
Combine 2-((S)-2-(p-methoxybenzylmercapto)-3-phenylpropionylamino)malonic acid (prepared by the method of Preparation 5, 0.476 g, 63% acid/37% sodium chloride, 0.74 mmol), and N-methylmorpholine (0.27 mL, 2.4 mmol), 2-methylphenylethylamine (0.25 mL, 1.7 mmol), dichloromethane (9 mL), and tetrahydrofuran (1mL). Add, 1-ethyl-3-(3-(dimethylamino)propyl)carbodiimide hydrochloric acid salt (0.314 g, 1.64 mmol) and 1 -hydroxybenztriazole hydrate (0.22 g, 1.64 mmol). After 1 day, concentrate in vacuo and partition the concentrated reaction mixture between an aqueous 5% sulfuric acid solution and ethyl acetate. Separate the layers and extract the organic layer with a saturated aqueous sodium bicarbonate solution and then brine. Dry the organic layer over Na2SO4, filter, and evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluting sequentially with 2/3 ethyl acetate/hexane and then 2/1 ethyl acetate/hexane to give the title compound.
