Reaction Steps
A solution of 568 mg (2 mmol) of 2,4-dimethoxy-4′-hydroxychalcone in ethanol (20 ml) was added 50 mg of platinum on charcoal (10%) and hydrogenated at 20 atm for 18 h. The colourless solution was filtered and concentrated in vacuo to give 606 mg, from which 143.7 mg (24%) of 3-(2,4-dimethoxyphenyl)-1-(4-hydroxyphenyl)propan-1-on was isolated by column chromatography over silica gel 60 (Merck 0.063-0.200 mm, 60 g) using petroleum ether-ethyl acetate (4:1, 500 ml, 3:1, 500 ml) as eluents, m.p. 126.4-127.4° C.
