Yield:1316311-27-9 87%

Reaction Conditions:

with tris-(dibenzylideneacetone)dipalladium⁽⁰⁾;tri-tert-butyl phosphine;sodium t-butanolate in o-xylene at 160; for 48 h;

Steps:

5
Pd2 (dba) 3 178.6 mg (0.20 mmol) and t-Bu3P 78.9 mg (0.39 mmol) of o-xylene dissolved in 50 ml after 10 bungan room temperature in agitation. Here 5,11-dihydroindolo[3,2-b] carbazole-5 g (19.51 mmol), bromobenzene, 3.37 g (21.46mmol), and t-BuONa 1.12 g (11.71 mmol) was added and the 160°C It was stirred at reflux for 48 hours. After the reaction was added to cold 20 ml of distilled water and extracted with ethyl acetate. After filtering the solvent was evaporated and dried with magnesium sulfate. After the column (5-phenyl -5,11- dihydroindolo[3,2-b] carbazole) Intermediate I-5 through a chromatography to obtain 5.62 g (yield 87%). MS-EI, m / e, 332.13 (calculated), 332.18 (measured value).
