Procedure

p-Toluenesulfonyl chloride (1.15 g, 0.006 mol) is added to 3-ethyl-5[(3-ethyl-2-benzothiazolinylidene)-1-hydroxyethylidene]rhodanine (1.82 g, 0.005 mol) in dry pyridine (15 ml). After stirring for 30 min. at room temperature, the solution is diluted with acetonitrile (25 ml), chilled and the dye collected, washed with acetonitrile, then ether. The yield is 0.74 g (39%)
