Yield:25287-05-2 97%
Reaction Conditions:
in N,N-dimethyl-formamide at 135 - 140;
Steps:
1.1
(1) Synthesis of Intermediate M:Weigh 1,98 g (0.01 mol) of 1,8 naphthalic anhydride and 2.16 g (0.01 mol) of p-phenylenediamine in a 50 mL round bottom flask and add 30 mL of DMF.Reflux at 135~140°C for 22~24 hours,A brick red precipitate was formed; it was then recrystallized from water and DMF and suction filtered to give intermediate M-4-aminophenyl-functionalized 1,8-naphthalenediimide derivative. Yield: 97%.
