Versuchsvorschrift

2-(2,4-Dimethyl-benzoylamino)-indan-2-carboxylic acid ethyl ester (414 mg, 1.23 mmol) is dissolved in EtOH (15 mL), and solid KOH (1.42 g, 24.7 mmol) and water (1.5 mL) are added. The mixture is stirred at RT for 30 min then concentrated in vacuo. The residue is dissolved in water (10 mL) and acidified with concentrated HCl until no more white solid precipitated. The solid is collected by vacuum filtration to give product (275) as white solid (350 mg, 92%).
