A mixture consisting of 3.3 grams of 4-(4-pyridinyl)butanamine, 6.5 grams of 2-methylthiobenz (cd)indole hydriodide, and 200 ml of ethanol. Cooling to room temperature failed to effect precipitation, so that solution was concentrated to 100 ml volume and cooled at -10° C. The precipitate that formed was collected, washed with ethanol, and dried. The yield of title compound was 6.1 grams; mp 197° C.-199° C. with decomposition.
