Reaction Steps

5.53 g of triethylamine was added to 6.03 g of 2-aminomethyl-5-[4,5-dihydropyridazin-3(2H)-on-6-yl]indane suspended in 60 ml of 1,3-dimethyl-2-imidazolidinone, and then 5.10 g of propanesulfonyl chloride dissolved in 20 ml of tetrahydrofuran was added to the mixture. The resulting mixture was stirred at room temperature for 30 minutes. The reaction mixture was poured into ice water, and crystals precipitated were collected by filtration. The precipitated crystals were recrystallized from methanol-acetonitrile to obtain 5.34 g of 2-(propylsulfonylaminomethyl)-5-[4,5-dihydropyridazin-3(2H)-on-6-yl]indane
