実験手順

To a suspension of 4-Hydroxy-5-methyl-indan-1-one (8 gm) in Methanol (80 ml), added 10% w/w Pd—C. Hydrogenation was carried out for 5 hours at 55-60° C. in an autoclave at 200-250 psi using Hydrogen gas. The reaction mixture was filtered through hyflow bed and filtrate was distilled under vacuum to give a 6.0 gm of desired product as white solid.
