Procedure

6,10,10-Trimethylpyrido[1,2-a]indolium perchlorate (0.62 g.) and 5-anilinomethylene-1,3-diethyl-2-thiobarbituric acid (0.6 g.) are dissolved in acetonitrile. Tetramethylguanidine (0.23 g.) is added and the reaction mixture is stirred at room temperature overnight. The precipitated dye is filtered off and recrystallized from acetonitrile. The λmax of the product in a mixture of pyridine and methyl alcohol is 513 nm.
