Abstract: | Treatment of 5-methylmercapto-1,4-benzodiazepine (I) with hydrazine hydrate gave the 5-hydrazino derivative (II, R = H) which, in turn, was conveniently cyclized to the title compounds. Another method for the synthesis of triazolo [4,3-d] [1,4] benzodiazepines (III) is also described. |
