Reaction Steps

Triethylamine (1.47 g) was added to 15 ml of a suspension containing 1.57 g of 2-aminomethyl-5-[4,5-dihydropyridazin-3(2H)-on-6-yl]indane suspended in 1,3-dimethyl-2-imidazolidinone, and the mixture was stirred at room temperature for 10 minutes. Then, 0.83 g of butyryl chloride dissolved in 8 ml of tetrahydrofuran was added dropwise to the mixture, and the resulting mixture was stirred for 1 hour. The reaction mixture was poured into ice water, and crystals precipitated were collected by filtration. The crystals obtained were washed with water, dried and then recrystallized from ethyl acetate-methanol to obtain 1.47 g of 2-(butyrylamino)methyl-5-[4,5-dihydropyridazin-3(2H)-on-6-yl]indane.
