Participants

Reaction Steps

To a stirred ice-cold solution of the above amide (400 mg, 1.9 mmol) in ether (20 mL), was added lithium aluminium hydride (1 M in THF, 4 mL). After stirring the ice-cold mixture for 1 h, excess reducing agent was quenched by the careful addition of 1N sulfuric acid (10 mL). The reaction mixture was stirred for 5min, the ether layer was decanted and the remaining solid was washed with ether (100 mL). The combined ether extract was washed with water, dried over anhydrous sodium.sulfate, and evaporated to give indane 2-carboxaldehyde as a light brownish oil which was used without further purification in the next step.
