Reaction Steps

A solution of 5-propyl-1-{6-[2-(1H-tetrazol-5-yl)-phenyl]pyridin-3-ylmethyl}-1H-pyrazole-3-carboxylic acid (20 mg, 0.05 mmol), HATU (19.5 mg, 0.0514 mmol) and DIPEA (44.7 uL, 0.257 mmol) in DMF (1.59 mL, 20.5 mmol) was stirred to pre-activate the acid. After 30 minutes, (R)-3-amino-4-(2-trifluoromethylphenyl)butanoic acid.HCl (14.6 mg, 51.4 μmol)) was added. The resulting solution was stirred overnight. The mixture was concentrated, re-dissolved in water/MeCN/TFA and purified using reverse phase liquid chromatography to yield the title compound (21.1 mg; 100% purity) as a TFA salt. MS m/z: [M+H]+ calcd for C31H29F3N8O3, 619.23. found 619.6.
