Synthesis of 1-Phenyl-1H-pyrazolo-quinoxaline (1-Phenylflavazole) Derivatives Substituted at 3-Position

3-Amino-, 3-chloro- and 3-hydroxy-1-phenyl-1H-pyrazoloquinoxalines (6,9 and 12) have been prepared starting from ethyl 2-hydroxyquinoxaline-3-carboxylate (1).The 3-amino derivative (12) is also obtained from a Hofmann reaction of 1-phenyl-1H-pyrazo
