実験手順

To a solution of 4-(4'-dimethylaminophenyl)-2,6-diphenylthiapyrylium chloride, 8.07 g, in a hot mixture of water, 400 mls, and ethanol, 100 mls, is added a solution of Methyl Orange, E. K. 432, 6.8 g, in hot water, 200 mls, with stirring. The mixture is stirred for 10 minutes and then is cooled and filtered, the filtrate being orange-red in color. The solid product is taken up in boiling nitromethane, filtered hot, evaporated down somewhat, and diluted with ethanol. The solid which crystallizes out overnight is filtered off. Yield: 9.3 g. of product having structural formula II noted above and exhibiting light absorption maxima (when dissolved in ethanol) at 582 and 427 nm.
