Reaction Steps

A solution of carbon disulfide (13.8 g) in absolute ethanol (100 ml) is added to a mixture of triethylamine (18.5 g), p-aminophenol (20 g) and absolute ethanol (400 ml). After the addition is completed, the reaction exotherms from 24° C to 29° C over a period of one hour and a tan solid is formed. The mixture is stirred one additional hour, cooled and filtered. Yield 39.8 g, of a tan solid (76% of theory), melting point 214° C to 217° C.
