Procedure
To a solution of 4-Hydroxy-indan-5-carbaldehyde (5 gm) in Methanol (80 ml), 10% wt/wt Palladium-charcoal (500 mg) was added. The hydrogenation was carried out for 8 hours at 55-60° C. in an autoclave at 240-250 psi using Hydrogen gas. The reaction mixture was filtered through hyflow bed and distilled under vacuum to give 4.0 gm of title compound as a solid.
