In dimethyl sulfoxide; at 70℃; for 10h;Inert atmosphere; Schlenk technique; | General procedure: To a schlenk tube (15 mL) containing a solution of <strong>[32566-01-1]2-(1H-indol-2-yl)aniline</strong> 3a (0.4 mmol) in DMSO (2 mL) was added 2-bromobenzaldehyde 4 (0.44 mmol) under nitrogen atmosphere.Then, the reaction mixture was stirred at 70C for 10 h until <strong>[32566-01-1]2-(1H-indol-2-yl)aniline</strong> 3a was consumed completely. Next, Pd(PPh3)2Cl2(0.02 mmol), [(t-Bu)3PH]BF4 (0.06 mmol) and Et3N (1.2 mmol) wereadded into the above reaction system under CO (1 atm) atmo-sphere. After being stirred at 120C for 5 h, the resulting mixturewas quenched with NH4Cl and extracted with ethyl acetate. Thecombined organic layer was washed with H2O and brine, and thendried over anhydrous Na2SO4. The solvent was removed underreduced pressure and the residue was puried by column chro-matography on silica gel (petroleum ether/ethyl acetate 5:1) toafford the corresponding indolo[1,2-c]isoindolo[2,1-a]quinazolin-5(16aH)-one 2. |
