反応手順
Dissolve 2-(carboethoxy)indan (6.49 g, 34.1 mmol) in ethanol (95%, 150 mL) and water (75 mL). Add potassium hydroxide (9.5 g, 0.17 mol) and stir at room temperature for 1 hour. Partition between water (150 mL) and ethyl ether (2×150 mL). Acidify the aqueous phase with hydrochloric acid to pH 1. Extract with methylene chloride (2×150 mL), dry (Na2SO4) and evaporate the solvent in vacuo to give 2-indancarboxylic acid as a tan solid (3.82 g, 69%).
