Reaction Steps

A mixture of 2-(2-Chloro-2-propenyl)-1,3-diethyl-1H-imidazo[4,5-b]quinoxalinium perchlorate 2.00 g (0.005 mole) and dry acetonitrile (20 ml) is stirred astriethylamine (1.50 g) is added in one portion to give a clear solution from which solid soon begins to separate. After 1 minute, the solid is collected, washed with several small portions of acetonitrile and dried invacuum at room temperature. Yield 0.63 g (48%). m.w. 264. The elemental analysis, infrared and nuclear magnetic resonance spectral support the assigned structure.
