Reference of 446292-07-5,Some common heterocyclic compound, 446292-07-5, name is (R)-2-(2-Hydroxy-3-((4-(3-oxomorpholino)phenyl)amino)propyl)isoindoline-1,3-dione, molecular formula is C21H21N3O5, 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.
In a four neck round bottom flask, charged dichloromethane (3400ml), 2-((2R)-2-Hydroxy-3- {[4-(3-oxo-4-morpholinyl)phenyl]amino}propyl)-lH-isoindole-l,3(2H)-dione (340 g) and Nu,Nu’ -dicarbonyldiimidazole (209.13 g) at 25 to 30C. The obtained reaction mass then stirred for 8hr. at 25 to 30C. Reaction mass is concentrated under reduced pressure to obtain residue. Added tetrahydrofuran (1700 ml) to residue. The obtained mixture is heated to 40 to 45C for 30 minutes followed by cooling to room temperature. Finally obtained solid is filtered off and washed by tetrahydrofuran(170 ml) Yield =93.55%
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route (R)-2-(2-Hydroxy-3-((4-(3-oxomorpholino)phenyl)amino)propyl)isoindoline-1,3-dione, its application will become more common.
