Application of 56341-37-8, 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. 56341-37-8, name is 6-Chlorooxindole belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
6-Chloro-1,3-dihydro-2H-indol-2-one (1.31 g, 7.85 mmol) and the compound (2.01 g, 7.85 mmol) obtained in Step 2 above were dissolved in methanol (40 ml) at room temperature and N,N-diisopropylethylamine (0.21 ml, 1.25 mmol) was added. After heating to reflux for 24 hours, saturated sodium bicarbonate solution was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with brine and then dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography [n-hexane:ethyl acetate=4:1 (v/v)] to give 2.53 g (82%) of the title compound as an orange solid.MS (FAB) m/z: 405 (M+H)+.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 6-Chlorooxindole, other downstream synthetic routes, hurry up and to see.
