実験手順
5-Fluoro-2-[3-methyl-2-((E)-propenyl)-benzoylamino]-indan-2-carboxylic acid (154) (270 mg, 0.76 mmol) is dissolved in absolute EtOH (15 mL) by heating. The resulting solution is cooled down to RT under argon and then is added the catalyst, Pd—C (5 wt. % Pd, 125 mg, 5.9% mmol). The resulting reaction mixture is moved to the Paar apparatus to run hydrogenation: 50 psi, 50° C., overnight. The catalyst is removed by filtration through a pre-column (10 g silica gel) and washed with EtOH. The combined organic solution is concentrated in vacuo. The residue is purified by HPLC to give a pure product (155) as white solid (210 mg, 78%).
