Participants

Reaction Steps

210 mg (0.4 mmol) of (S)-3-{[5-(2-cyano-benzyloxy)-1-(2-fluoro-phenyl)-1H-pyrazole-3-carbonyl]-amino}-3-o-tolyl-propionic acid ethyl ester were dissolved in a mixture of THF, MOH and water (2 ml each), lithium hydroxide (28.7 mg, 1.2 mmol) was added, and the mixture was stirred for 3 h at room temperature. After evaporation of the solvent the residue was subjected to aqueous work-up using EA and a 10% aqueous solution of citric acid. After evaporation of the organic phase the residue was subjected to column chromatography (silica gel, DCM/MOH 10:1) to give 45 mg (23%) of the title compound.
