実験手順

Thionyl Chloride (0.95 mL, 13.0 mmol) was added to a room temperature solution of indane-1-carboxylic acid dissolved in 20 mL of dichloromethane. The reaction mixture was stirred at room temperature for 35 minutes after which time the volume was reduced by approximately 50% via a rotovap. Then 20 mL of methanol was added and the reaction was stirred at room temperature for 3 hours. Evaporation of the solvent and column chromatography (9/1 hexanes/EtOAc) afforded of methyl indane-1-carboxylate (2.2 g, 100%) as a colorless oil.
