## Abstract magnified image Amination of 4‐hydroxypyridocarbazolones **1** with aniline or benzylamine gave in good yields 4‐amines **3**. With piperidine in a sealed tube from 4‐hydroxy‐ or 4‐chloro‐5‐alkylpyridocarbazolones **1** or **4** ring opened 1‐acylcarbazoles **5** were obtained. Only 4‐
4-Hydroxy-5-phenylpyrido[3,2,1-jk]carbazol-6-ones (4, 5), which were obtained from carbazoles 1 and malonates 2 or 3, were converted to reactive intermediates such as 4-chlorides 9 or 4-tosylates 10, which gave in turn 4-azido-5-phenyl derivatives 11. 5-Alkyl-4-azides 11 were not obtained in this ma
