1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → 3-(4-{2-[5-Ethyl-2-(4-trifluoromethyl-phenyl)-thiazol-4-yl]-propionylamino}-2-methyl-phenyl)-propionic-acid Methyl Ester

Participants

Reaction Steps

To a mixture of 2-[5-Ethyl-2-(4-trifluoromethyl-phenyl)-thiazol-4-yl]-propionic acid (0.35 mmol), 3-(4-Amino-2-methyl-phenyl)-propionic acid methyl ester (0.35 mmol), and DMAP (0.01 g, 0.082 mmol) in CH2Cl2 (5 mL) is added EDCI (0.08 g, 0.42 mmol). After stirring for 2 h at RT, the mixture is concentrated. The residue is redissolved in EtOAc, and the organics are washed with 1N HCl (1×), 2N NaOH (2×), water, and brine, and dried with MgSO4. The crude material is purified by flash chromatography to yield the title compound.
