95% | To a stirred solution of bromobenzaldehyde 1b (1.0 g, 4.6 mmol) and methyl carbamate (524 mg, 7.0 mmol) in acetonitrile (12 mL), were added sequentially TFA (0.71 mL, 9.3 mmol) and tert-butyldiemthylsilane (TBDMSH) (1.53 mL, 9.3 mmol) and the resulting solution was stirred at 80 C for 6 h. The reaction mixture was concentrated in vacuo and the residue dissolved in a mixture of THF, MeOH and aq. LiOH [1.95 g, 46.5 mmol in H2O (5 mL)] (1:1:1, total 15 mL) and heated at 80 C for 16 h. The reaction mixture was cooled to RT and then treated with aqueous NaOH [700 mg in H2O (10 mL)] and the mixture was extracted with ethyl acetate (3 × 20 mL). The combined organic layers were washed with saturated NaCl solution, dried (Na2SO4), and filtered. Evaporation of the solvent and purification of the crude material by flash chromatography (short column, ethyl acetate/hexane, 1:1 to 100% ethyl acetate, then 5:95 methanol/ethyl acetate to 10:90 methanol/ethyl acetate) furnished the benzylamine 3b (960 mg, 95%) as pale yellowish viscous liquid. 1H NMR (400 MHz, CDCl3): = 7.40 (d, J = 8.6 Hz, 1H, Ar-H), 6.93 (d, J = 3.0 Hz, 1H, Ar-H), 6.67 (dd, J = 8.6, 3.0 Hz, 1H, Ar-H), 3.86 (s, 2H, CH2NH2), 3.78 (s, 3H, OCH3), 2.12 (br. s, 2H, CH2NH2); 13C NMR (100 MHz, CDCl3): = 159.3 (C), 142.5 (C), 133.4 (CH), 114.8 (CH), 114.1 (CH), 113.7 (C), 55.4 (OCH3), 46.8 (CH2NH2); HRMS (ESI) calcd for C8H11BrNO [M+H]+ 216.0018, found 216.0017. |

92% | With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In 1,4-dioxane; for 23h;Reflux; | To a degassed solution of 2-bromo-5-methoxybenzaldehyde (1.5 g, 7.04 mmol, Fluorochem) and trimethylboroxine (0.98 mL, 7.04 mmol) in 1,4-dioxane (80 mL) was added potassium carbonate (2.91 g, 21.1 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.813 g, 0.70 mmol). The mixture was heated under reflux for about 20 h, then more tetrakis(triphenylphosphine)palladium(0) (0.200 g, 0.17 mmol) and trimethylboroxine (0.25 mL, 1.8 mmol) were added and the mixture was heated under reflux for about another 3 h. After cooling to rt the mixture was filtered over diatomaceous earth and concentrated in vacuo. The residue was purified by column chromatography (SiO2, diethyl ether/hexanes 1:3) to give 5-methoxy-2-methyl-benzaldehyde (0.97 g, 92%) as a colorless liquid. 1H-NMR (CDCl3, Bruker 400 MHz) 2.60 (3H, s); 3.83 (3H, s); 7.04 (1H, dd, J=8.5 Hz, 2.4 Hz); 7.16 (1H, d, J=8.5 Hz); 7.33 (1H, d, J=2.4 Hz); 10.2 (1H, s). |

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. |
