Route of Synthesis (ROS)
| Conditions | Yield |
| With manganese(IV) oxide In dichloromethane for 72h; Experimental Procedure To a stirred solution of azaindoline 5 (7.00 g, 35.2 mmol) in CH2C12 (664 ML) was added activated MnO2 (3.06 g, 35.2 MMOL), AND PROGRESS of the reaction was monitored BY LH EMR of reaction aliquots. After 3 days the mixture was filtered through A pad of silica, and the pad was washed with EtOAc. The filtrates were concentrated to afford the azaindole 27 (6. 98 g, 100 percent) as A brown solid. 1H NMR data as in Method 1. | 100% |
| With manganese(IV) oxide In toluene for 4h; Reflux; Experimental Procedure The 84.8 g of the 5-bromo-7-azaindoline product obtained in step 4 was dissolved in 400 mL of toluene,221.5 g of manganese dioxide was added,Heating reflux reaction 4h;Step 6) The reaction solution obtained in Step 5 was cooled to room temperature,filter,The filter cake was washed twice with dichloromethane,Combine organic phase,dry,Concentrated 5-bromo-7-azaindole crude product,The product was crystallized from a petroleum ether-ethyl acetate mixed solution of ΡΕ / ΕΑ = 10: 1 to give 75 g of 5-bromo-7-azaindole,Yield 90percent. | 90% |
| With activated carbon fiber catalyst In 5,5-dimethyl-1,3-cyclohexadiene at 100℃; for 8h; Solvent; Experimental Procedure a) 30g (0.151mol) of 5-bromo-7-azaporphyrin, 60g of activated carbon fiber catalyst, 264g of xylene into the reaction flask, stirring evenly, to obtain a reaction mixture G;b) The reaction mixture G at 100 °C, oxygen flow 200mL/min, reaction 8h, chromatographic monitoring of the disappearance of raw materials;c) Filtration, filter out activated carbon fiber catalyst, obtain organic layer H, recover solvent, get 5-bromo-7-azaindole crude product, recrystallize from methanol to obtain product 25.37g, yield 85.43percent, content ≥99percent . | 85.43% |
