Product 1

HCID 58102914(2R,3R)-2-hydroxy-3-(1-((2'-(N-(methoxycarbonyl)-sulfamoyl)biphenyl-4-yl)methyl)-5-propyl-1H-pyrazole-3-carboxamido)-4-phenylbutanoic AcidYield 95%

Procedure

A solution of 1-((2′-(N-(methoxycarbonyl)sulfamoyl)biphenyl-4-yl)methyl)-5-propyl-1H-pyrazole-3-carboxylic acid (40.2 mg, 87.8 μmol), DIPEA (91.8 μL, 527 μmol) and HATU (33.4 mg, 87.8 μmol) in DMF (0.4 mL, 4 mmol) was stirred to pre-activate the acid. After 1 minute, (2R,3R)-3-amino-2-hydroxy-4-phenylbutyric acid (17.1 mg, 87.8 μmol) was added, and the mixture was stirred for 10 minutes. The reaction was quenched by adding 1 N HCl and extracted with DCM. The organic layer was added to AcOH (1 mL) and evaporated in vacuo. The material was then purified by preparative HPLC to yield the title compound (10 mg, 95% purity). MS m/z: [M+H]+ calcd for C32H34N4O8S, 635.21; found 635.20.
