Conditions

Temperature
40 °C

Procedure

A solution of 1-[6-(2-acetylsulfamoylphenyl)pyridin-3-ylmethyl]-5-propyl-1H-pyrazole-3-carboxylic acid (100 mg, 226 μmol) in DMF (7.0 mL, 90 mmol) was added to HATU (85.9 mg, 226 μmol). The resulting mixture was stirred for 5 minutes before (2R,3R)-3-amino-2-hydroxy-4-phenylbutyric acid.HCl (52.4 mg, 226 μmol) and DIPEA (315 μL, 1.8 mmol) were added. The resulting solution was heated at 40° C. overnight. The mixture was concentrated, re-dissolved in water/MeCN/TFA and purified using reverse phase liquid chromatography to yield the title compound (48 mg; 91% purity) as a TFA salt. MS m/z: [M+H]+ calcd for C31H33N5O7S, 620.21. found 620.4.
