Procedure

6-Benzyloxy-2-(2-methylphenyl)-4H-chromen-4-one (mp 115°) is hydrogenated in ethyl acetate over palladium (10% on charcoal) at atmospheric pressure and room temperature for 1 hour. The mixture is filtered over celite, and the filtrate is evaporated in vacuo. The title compound is obtained (colourless crystals; mp 180°).

Workup

  1. filtrationThe mixture is filtered over celite
  2. customthe filtrate is evaporated in vacuo
