Reaction Steps

The evaporation residue obtained in step (c) is dissolved in 300 ml of 94% ethanol. Then 2 g of 5% palladium-on-charcoal are added. The reaction mixture is stirred at room temperature under a hydrogen atmosphere until one equivalent of hydrogen is consumed. The catalyst is filtered off. The solvent is evaporated, and the residue is crystallized from toluene. The yield is 12.7 g (38%) from desoxybenzoin) of a product having m.p. 192°-4° C.
