Reaction Steps

(2S,4R)-5-Biphenyl-4-yl-2-hydroxymethyl-2-methyl-4-[(3H-[1,2,3]triazole-4-carbonyl)-amino]-pentanoic acid (100 mg, 245 μmol, 1.0 eq.), EDCI (52 μL, 294 μmol, 1.2 eq.) and HOBt (39.7 mg, 294 μmol, 1.2 eq.) were dissolved in DCM (5 mL). After stirring for 10 minutes, 4-hydroxymethyl-5-methyl-[1,3]dioxol-2-one (127 mg, 979 μmol, 4.0 eq.) was added. The mixture was stirred for 1 hour and 4-methylmorpholine (40.4 μL, 1.5 eq.) was added. After 1 hour, the crude material was dissolved in AcOH and purified by preparative HPLC to yield the title compound (20 mg). MS m/z [M+H]+ calc'd for C27H28N4O7, 521.20. found 521.4.
