実験手順
Dissolve 2-carboxy-indan (2.5 g, 15.4 mmol) in methanol and cool to 0° C. Saturate with hydrochloride gas then add 2,2-dimethoxypropane (2-3 mL). Stir overnight then evaporate the solvent in vacuo. Purify by silica gel chromatography (2:1 methylene chloride/hexane) to give 2-carbomethoxy-indan as a water white oil. (2.04 g, 75%).
