Reaction Conditions

Reaction Steps

16.5 g of 1,5-bis(mesitylamino)-3,7-dibromoanthraquinone are suspended at RT in 50 ml of DMF and heated to 120° C. After cooling to 50° C., a suspension of 8.5 g of sodium thiophenolate in 25 ml of DMF is added thereto. The mixture is then heated to 120° C. again and stirred at that temperature for 1.5 hours. After cooling the mixture to 60° C., 100 ml of methanol are added and the mixture is stirred overnight at RT. The precipitate is filtered off, washed with a methanol/water mixture (1:1) and dried in vacuo.
