These common heterocyclic compound, 446292-07-5, name is (R)-2-(2-Hydroxy-3-((4-(3-oxomorpholino)phenyl)amino)propyl)isoindoline-1,3-dione, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Formula: C21H21N3O5
2641 g of 2-((2R)-2-hydroxy-3-{[4-(3-oxo-4-morpholinyl)phenyl]amino}propyl)-1H-isoindole-1,3(2H)-dione (V) are suspended in 22 l of toluene and, at 19 C., 1300 g of N,N-carbonyl-diimidazole are added. The reaction mixture is subsequently heated under reflux for one hour and then, at 60 C., 4.5 l of ethanol are added. After cooling to 25 to 30 C., the precipitated reaction product is filtered off with suction, washed with ethanol and then dried. Yield: 2756 g; equivalent to 97.9% of theory. Melting point: 220.5 C.
The synthetic route of (R)-2-(2-Hydroxy-3-((4-(3-oxomorpholino)phenyl)amino)propyl)isoindoline-1,3-dione has been constantly updated, and we look forward to future research findings.
