Participants

Reaction Steps

1,2,3-Triazole-4-carboxylic acid (130 mg, 1.2 mmol, 1.2 eq.) and HATU (400 mg, 1.1 mmol, 1.1 eq.) were dissolved in DIPEA (167 μL) and the resulting mixture was stirred for 5 minutes at room temperature in DMF (0.2 mL). DIPEA (3 eq.) and (2S,4R)-4-amino-5-biphenyl-4-yl-2-hydroxymethyl-2-methyl-pentanoic acid (300 mg, 957 μmol, 1.0 eq.) dissolved in DMF (0.2 mL) was added, and the resulting mixture was stirred for 15 minutes. The reaction was quenched with AcOH and the product was purified by preparative HPLC then lyophilized to yield the title compound (120 mg, 95% purity). MS m/z [M+H]+ calc'd for C22H24N4O4, 409.18. found 409.4.
