The chemical industry reduces the impact on the environment during synthesis 1127-59-9, name is 7-Methylindoline-2,3-dione, I believe this compound will play a more active role in future production and life. 1127-59-9
General procedure: Isatin 1 (3 mmol), malononitrile (3 mmol), 4-hydroxy-6-methylpyridin-2(1H)-one 2 (3 mmol) were refluxed for 60 minin ethanol (5 ml) with sodium acetate (10 molpercent) or in pyridine (without any catalyst). After the reaction was finished, the solid was filtered,washed with ice ethanol and dried to isolate pure products 3. For their characteristics, see Online Supplementary Materials.
