In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 446292-08-6 as follows. category: indolines-derivatives
10 g (0.024 mol) of 2-({(5S)-2-oxo-3-[4-(3-oxo-4-morpholinyl)phenyl]-1 ,3-oxazolidin-5- yl}methyl)-1 H-isoindole-1 ,3(2H)-dione (II), 7.12 mL of methylamine (40% aqueous solution, 0.083 mol) and 150 mL of methanol were charged in a 1 L autoclave and heated to reflux temperature (65.0C) for 1 hour. Afterwards, the reaction mass was cooled to 25-30C and transferred to another flask. Then, 9.9 g (0.095 mol) of malonic acid in 50 mL of methanol were added dropwise within 30 min. Then, the reaction mass was stirred to 25-30 C for 24 hours. The solid obtained after filtration was stirred in 100 mL of ethanol at 25 C for 1 hour. Finally, the solid obtained was filtered off and dried under vacuum at 50 C.Yield: 5.9 g. Molar yield: 62.89%. HPLC purity: 99.15%.
