Procedure

0.5 g of 1-(2,4-dimethoxy-6-aminophenyl)-3-(4-hydroxyphenyl)-prop-2-en-1-one, 20 mL methanol, and 1 g of palladium on carbon were mixed; and to the mixture was added 50 μL of sodium borohydride and placed under vacuum. The reaction was continued for 30 minutes or until hydrogen evolution ceased. The reaction mixture was diluted with 100 mL of water. Pale yellow to tan crystals of 1-(2,4-dimethoxy-6-aminophenyl)-3-(4-hydroxyphenyl)-propan-1-one formed. The crystals were obtained from the mixture via centrifugation at 1000×g for 10 minutes. The crystals were resuspended in water, and centrifugation was repeated.
