Procedure

A solution of concentrated sulphuric acid (d=1.83; 0.2 cc) in ethanol (5 cc) is added to a solution of N-(5-phenacylthio-1,2-dithiol-3-ylidene)-morpholinium chloride (0.75 g) in ethanol (20 cc) under reflux. After cooling to a temperature of about 10° C., the insoluble product formed is filtered off and washed with ethanol (4 cc). After drying, N-(5-phenacylthio-1,2-dithiol-3-ylidene)-morpholinium hydrogensulphate (0.8 g), melting at 192° C., is obtained.
