Product Details of 20780-72-7

General procedure: A solution of 2-nitrobenzamides 1 or bis(2-nitrobenzamides) 4 (1 mmol), isatins 2 or acenaphthylene-1,2-diones 6 (1 mmol), and SnCl2*2H2O (4 mmol) in EtOH (5 mL) was stirred at reflux for 3-5 h. After this period, the TLC analysis of the mixture showed the reaction to be completed. The mixture was quenched with 3percent HCl (10 mL) and filtered to yield a crude product, which was purified by recrystallization from 95percent ethanol and DMF.

The synthetic route of 20780-72-7 has been constantly updated, and we look forward to future research findings.
