Reaction Steps

100 g of 2,5-Dimethoxy-3'-nitrobenzophenone was dissolved in 1.3 liters of ethanol. With the addition of a 10% palladium on carbon catalyst, the solution was charged in an autoclave, and hydrogenated for 8 hours at 130° C with an initial hydrogen pressure of 100 kg/cm2. The filtrate obtained on removal of the catalyst was concentrated to obtain white crystals. Filtration and air drying provided 57 g of the subject compound, which had a melting point of 132° to 134° C.
