Procedure

1,2,3,4,6,7-Hexahydro-13-methyldibenzo[a,f]quinolizinium perchlorate (0.7 g) and 5-anilinomethylene-1,3-diethyl-2-thiobarbituric acid (0.6 g) were dissolved in acetonitrile and tetramethylguanidine (0.22 g) was added. The precipitated dye was collected by filtration and recyrstallized from dimethylformamide. Yield 0.4 g (44%), m.p. 320°, λmax in pyridine 522 nm, ε = 8.2 × 104.
