実験手順

A reaction mixture of 4-chloro-1-methyl[1,2,4]triazolo[4,3-a]quinoxaline (1.0 g; 0.004 mole) and cyclopentanamine (1.17 g; 0.013 mole) in 15 ml of DMF was stirred at room temperature for 20 hours. The reaction mixture was poured over ice-water and the precipitated solid was filtered, washed with water and dried affording 0.9 g (74%) of N-cyclopentyl-1methyl-[1,2,4]triazolo[4,3-a]quinoxalin-4-amine having a mp of 196°-198° C.
