Reaction Steps

3,5-Pyrazoledicarboxylic acid (37.7 mg, 241 μmol, 1.0 eq.), EDCI (42.7 μL, 241 μmol, 1.0 eq.), 4-methylmorpholine (53.1 μL, 2.0 eq.) and 1 HOBt (32.6 mg, 241 μmol, 1.0 eq.) were combined in DMF (0.2 mL) and stirred for 5 minutes at room temperature. A predissolved solution of (2S,4R)-4-amino-5-(3′-fluorobiphenyl-4-yl)-2-hydroxymethyl-2-methyl-pentanoic acid (80 mg, 240 μmol, 1.0 eq.) and 4-methylmorpholine (53.1 μL) in DMF (0.3 mL) was added and the resulting mixture was stirred for 15 minutes. The reaction was quenched by adding AcOH and the product was purified by preparative HPLC and lyophilized to yield the title compound (25 mg). MS m/z [M+H]+ calc'd for C24H24FN3O6, 470.17. found 470.4.
