Vorschrift

2 g of 1,3-dimethyl-6-[4-(3-[4-nitrophenoxy)propyl)piperazin-1-yl]-2,4(1H,3H)-pyrimidinedione (Compound f) obtained in Reference Example 4 was suspended in 300 ml of methanol and 500 mg of 10% Pd/c solution was added to the suspension, and hydrogenation was then carried out at ordinary pressure for 30 minutes. The catalyst was removed by filtration, and the solvent was distilled off, thereby obtaining 1.54 g of 6-[4-(3-[4-aminophenoxy)propyl)piperazin-1-yl]-1,3-dimethyl-2,4(1H,3H)-pyrimidinedione.
