実験手順

A mixture of 5-aminobenzotriazole (0.78 g), 4-(5-hydroxy-3-methyl-1-phenylpyrazol-4-ylazo)benzoyl chloride (2.0 g) and N,N-dimethylaniline (0.71 g) in dry tetrahydrofuran (15 ml) was stirred overnight and water (50 ml) was added. The precipitate was filtered and crystallized in aqueous pyridine (1.9 g), m.p. 285° decomp., λmax (methanol)=396 nm.

後処理

  1. filtrationThe precipitate was filtered
  2. customcrystallized in aqueous pyridine (1.9 g)
