Sodium hydride → HCID 131733310, compound

Participants

Reaction Steps

To a suspension of 1 g of NaH (60%) (25.08 mmol) in 30 mL of MTBE there are added, dropwise, a solution of 5 g of tert-butyl 3-morpholino-3-oxopropanoate (21.81 mmol) in 20 mL of anhydrous MTBE. This suspension is stirred at ambient temperature for 1 hour and then the compound obtained in Step A is added in the form of a powder. The batch is stirred at 60° C. for 30 hours. 100 mL of saturated aqueous ammonium chloride solution are added. The resulting solution is extracted with dichloromethane. The organic phase is then dried over MgSO4, filtered and concentrated to dryness. After purification by chromatography over silica gel (dichloromethane/MeOH gradient), the expected product is obtained in the form of an oil.
