14 g of 1-amino-2-(5,6-dihydro-4H-1,3-oxazin-2-yl)-4-nitroanthraquinone, 5.4 g of potassium carbonate, 100 cc of N-methylpyrrolidone and 5.9 g of 4-chlorothiophenol are reacted as in Example 2. The reaction mixture is worked up as described in that example to give 9.2 g of 1-amino-2-(5,6-dihydro-4H-1,3-oxazin-2-yl)-4-(4-chlorophenylmercapto)-anthraquinone, corresponding to a yield of 51% of theory.
