実験手順

A RBF was charged with 13.9 mL of 1:1 AcOH:HBr and 4-ethyl-N-(4-methoxyphenyl)-6-phenylpyridazin-3-amine (1.27 g, 4.16 mmol). The flask was fitted with a reflux condenser and was heated at 140° C. for 4 h. Upon cooling, the reaction mixture was poured into ice water and brought to neutral pH by careful addition of 2M aqueous Na2CO3. The resulting precipitate was filtered, washed with water and dried under vacuum to provide 4-(4-ethyl-6-phenylpyridazin-3-ylamino)phenol as a tan solid. MS m/z=292 [M+H]+. Calc'd for C18H17N3O: 291.35.
