실험 절차

3-Bromo-4-fluorobenzoic acid (109 mg, 497 μmol, 1.0 eq.), DIPEA (273 μL, 3.2 eq.), HATU (189 mg, 497 μmol, 1.0 eq.), and (2R,3R)-3-amino-2-hydroxy-4-phenyl-butyric acid ethyl ester (129 mg, 497 μmol, 1.0 eq.) were combined in DCM (2 mL) and stirred for 1 hour. The crude reaction was then chromatographed (0-80% EtOAc/hexanes gradient) to yield (2R,3R)-3-(3-bromo-4-fluoro-benzoylamino)-2-hydroxy-4-phenyl-butyric acid ethyl ester.
