Synthèse Des Pyrazolyl-1 Benzimidazoles A Partir Des Dihydro-1,3(2H) Benzo[2,3-b] Diazepine-1,5 Ones-2
摘要:
AbstractHydrazinolysis of 4‐phenyl 1,5‐benzodiazepine 2‐thiones 2a‐2b gives N‐(5 (3)‐phenyl 3(5)‐pyrazolyl) 1‐amino 2‐aminobenzene 3a‐3b. The compounds 3a‐3b have been used as precursors to prepare the 1‐[(5)3‐phenyl (3)5‐pyrazolyl] benzimidazoles 5a‐5h.
