PROCEDURE

实验过程

A solution of 5-propyl-1-{6-[2-(1H-tetrazol-5-yl)phenyl]pyridin-3-ylmethyl}-1H-pyrazole-3-carboxylic acid (40 mg, 103 μmol), HATU (39.0 mg, 0.103 mmol) and DIPEA (89.4 uL, 514 μmol) in DMF (3.2 mL, 41.1 mmol) was stirred to pre-activate the acid. After 30 minutes, (R)-3-amino-4-(2-fluorophenyl)butanoic acid.HCl (24.0 mg, 103 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 (15.7 mg; 100% purity) as a TFA salt. MS m/z: [M+H]+ calcd for C30H29FN8O3, 569.23. found 569.2.
