Reaction Steps

1.51 g of propanal dissolved in 5 ml of methanol was added dropwise to 6.15 g of 2-aminomethyl-5-[4,5-dihydropyridazin-3(2H)-on-6-yl]indane dissolved in 60 ml of methanol. The mixture was stirred at room temperature for 30 minutes. Then, under ice cooling, 1.03 g of sodium borohydride was added to the mixture. The resulting mixture was stirred at the same temperature for 20 minutes and then stirred at room temperature for 1 hour. After methanol was removed, water was added to the residue, and the residue was extracted with ethyl acetate. After the organic layer was washed with water and dried, the solvent was removed. The residue was purified by silica gel column chromatography (solvent: chloroform-methanol (15:1)) to obtain 5.22 g of 2-(propylaminomethyl)-5-[4,5-dihydropyridazin-3(2H)-on-6-yl]indane.
