1-Hydroxy-1H-1,2,3-triazole-4-carboxylic acid (163 mg, 1.3 mmol) was combined with HCTU (523 mg, 1.3 mmol) and DMF, and stirred for 5 minutes at room temperature. DIPEA (661 μL, 3.8 mmol) and (2R,4R)-4-amino-5-(4-bromophenyl)-2-hydroxypentanoic acid ethyl ester (0.400 g, 1.26 mmol) were added, and the resulting mixture was stirred for 10 minutes. The mixture was evaporated under reduced pressure and purified (C18 column; 20-70% MeCN in water with 5% TFA) to yield the title compound (330 mg).
