The reaction of diethyl 2-hydroxyazulene-1,3-dicarboxylate with morpholine, pyrrolidine, piperidine, and dimethylamine in the presence of copper(II) acetate gave the respective 6-aminoazulene derivatives. Similarly, the reaction of cycloheptimidazol-2(1H)-one with morpholine gave the 6-ami-nocycloheptimidazole derivative, while the reaction with pyrrolidine gave the 4-(or 5-)aminocycloheptimidazole derivative.
