Vorschrift

4.9 g of commercial triethylammonium 5-(3-(5-cyano-1-ethyl-4-methyl-2,6-dioxo-1,6-dihydro-2H -pyridin-3-ylidene)propenyl-1-ethyl-6-hydroxy-4-methyl-2-oxo-1,2-dihydropyridine-3-carbonitrile (24a) was made to react with 0.8 g of ammonium acetate in 75 mL of acetic acid as described under (a). This gave 3.6 g of dye (24a).
