Reference of 6341-92-0, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6341-92-0, name is 6-Chloroisatin belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
General procedure: A mixture of isatins 1 (1 mmol), substituted 1H-pyrazol-5-amine 2 (1 mmol), 6-aminopyrimidine-2,4(1H,3H)-dione 3 or 6-amino-1,3-dimethylpyrimidine-2,4(1H,3H)-dione 5 (1 mmol), H2O(6 mL), and HOAc (2 mL) was placed in a 25-mL flask andstirred at 90 C (monitored by thin layer chromatography (TLC)) for about 7 h. Afterreaction completion, the mixture was cooled to room temperature and the precipitateobtained by filtration. Compounds 4 or 6 were further purified by recrystallizationfrom DMF.
The synthetic route of 6-Chloroisatin has been constantly updated, and we look forward to future research findings.
