Versuchsvorschrift

A mixture of 5-aminobenzotriazole (0.47 g), 4-(N,N-dimethylamino)-phenylazobenzoyl chloride, hydrochloride (1.13 g) and N,N-dimethylaniline (0.84 g) in dry tetrahydrofuran was stirred overnight and the resulting precipitate was filtered off and recrystallized in a dimethylformamide/water mixture to give pure dye, 0.73 g, m.p. 246°, λmax (methanol)=435 nm.
