Procedure

1,2,3-Triazole-4-carboxylic acid (14 mg, 124 nmol), DIPEA (86.3 mL, 496 nmol) and HATU (47.1 mg, 124 nmol) were combined in DMF (0.2 mL) and stirred for 5 minutes at room temperature. This was then combined with (2S,4R)-4-amino-5-biphenyl-4-yl-2-hydroxymethyl-2-methyl-pentanoic acid ethoxycarbonyloxymethyl ester (51 mg, 120 nmol). The resulting mixture was stirred for 15 minutes and the reaction was quenched with AcOH. The product purified by preparative HPLC and lyophilized to yield the title compound (5 mg; purity 90%). MS m/z [M+H]+ calc'd for C26H30N4O2, 511.21. found 511.6.
