Versuchsvorschrift

5-(4-Methoxyphenylazo)salicoyl chloride (1.46 g) in dry tetrahydrofuran (10 ml) was added dropwise with stirring to a solution of 5-aminobenzotriazole (0.67 g) in dry tetrahydrofuran (15 ml) and dimethylaniline (0.61 g). After 2-3 hours the mixture was poured into water and the solid removed by filtration. The product was crystallized in aqueous pyridine as yellow plates of the monohydrate (1.5 g, 81%), m.p. 275°-6°, λmax (methanol)=352 nm.
