Participants

Reaction Steps

2-(2-Cyclopentyl-2-phenyl-acetylamino)-indan-2-carboxylic acid ethyl ester (268) (1 g, 2.56 mmol) is dissolved in EtOH (50 mL) and set to stir at RT. To this solution is added 5M KOH (3 ml). The reaction mixture is stirred at RT overnight. After concentration in vacuo, the residue is dissolved in water (20 mL) and washed with EtOAc (20 ml). The phases are separated and the aqueous phase is acidified with concentrated HCl to pH 2. The solid precipitate is collected via filtration and dried under vacuum. The desired product (269) is obtained as white solid (710 mg, 71%).
