subsequently converted to 1,4‐benzodiazepines (3) by the modification of the known hexamethylenetetramine based cyclization reaction developed by Blazevic and Kajfez. Thus, obtained product (3) was reacted with a variety of alkyl halide using KOH in DMF to give 1‐substituted‐5‐(4‐fluorophenyl)‐1H‐benzo[e][1,4]diazepin‐2(3H)‐one (4a, 4b). To achieve 1, 3‐disubstituted 1, 4‐benzodiazepines (5a, 5b, 5c, 5d, 5e
随后将2-氨基-4'-氟-二苯甲酮(1)与氯乙酰氯反应生成2-氯N-(2-(4'-氟苯甲酰基)苯基)乙酰胺(2),然后将其转化为1,4-通过修饰由Blazevic和Kajfez开发的已知的以六亚甲基四胺为基础的环化反应,苯并二氮杂(3)。因此,使用DMF中的KOH ,将获得的产物(3)与各种卤代烷反应,得到1-取代的-5-(4-氟苯基)-1 H-苯并[e] [1,4]二氮杂-2-(3)H)-1(4a,4b)。要达到1,3-二取代1,4,-苯二氮卓(5a,5b,5c,5d,5e,5f,5g,5h,5i,5j,5k,5l,5m,5n,5o,5p,5q,5r,5s,5t),1-取代的-5-(4-氟苯基)-1在甲苯中存在KOH的情况下,用各种芳族醛处理H-苯并[e] [1,4]二氮杂-2-2(3 H)-one(4a,4b)。
