After about 6.5 parts of water was collected, there was added to the resulting mixture 26.3 parts of para-dibromobenzene and the mixture was heated to reflux. After 6 hours at reflux the reaction mixture was allowed to cool and 300 parts of water was added. There was obtained a tan colored solid which was filtered and washed with water several times. The product was then dried. There was obtained 34.7 parts of 1,4-dithiophenoxybenzene based on method of preparation.
