Yield:285129-85-3 88%
Reaction Conditions:
with toluene-4-sulfonic acid in ethanol at 100;Inert atmosphere;
Steps:
2.4.9. Synthesis of 10,13-dibromodibenzo[a,c]phenazine (9)
3,6-Dibromobenzene-1,2-diamine (3) (200 mg, 0.752 mmol) and phenanthrene-9,10-dione (391 mg, 1.88 mmol) were dissolved in the 25 mL ethanol at room temperature. The solution mixture was heated for few minutes and later on a catalytic amount of PTSA was added. The desired solid was precipitated with the PTSA addition. The mixture was refluxed at 100 °C overnight. The precipitate was filtered and washed with ethanol to obtain yellow solid (88% yield). 1H (400 MHz, CDCl3) δ (ppm): 9.41 (d, J = 1.5 Hz, 2H),8.50 (dd, J = 1.5, 2H), 7.96 (s, 2H), 7.75 (t, 4H). 13C NMR (100 MHz, CDCl3) δ (ppm): 143.4, 131.8, 130.07, 126.7, 123.3.
