Procedure

2-(3-Carboxy-propyl)benzoic acid (50 mg, 240 μmol, 1.0 eq.) was combined with DIPEA (134 μL, 3.2 eq.) and HATU (91.3 mg, 240 μmol, 1.0 eq.) in DCM (5 mL). (2R,3R)-3-Amino-2-hydroxy-4-(2-trifluoromethyl-phenyl)-butyric acid ethyl ester (69.9 mg, 240 μmol, 1.0 eq.) was added and the resulting mixture was stirred for 1 hour. The reaction was quenched by adding saturated NH4Cl and the product was extracted with DCM, dried, evaporated, and purified by preparative HPLC to yield the title compound (40 mg, 100% purity). MS m/z [M+H]+ calc'd for C24H26F3NO6, 482.17. found 482.
