Morpholine → HCID 58930433, compound

Participants

Reaction Steps

To a solution of 42 (950 mg, 4.35 mmol) and morpholine (455 μL, 5.21 mmol) in dry 1,2-dichloroethane (10 mL) at room temperature was added AcOH (2 drops) followed by NaBH(OAc)3 (1.1 g, 5.21 mmol) and the mixture was stirred for 16 h. A solution of 10% K2CO3 was added to the reaction mixture followed by dichloromethane and the phases were separated. The aqueous phase was extracted with CH2Cl2 and organic layer was dried over anhydrous Na2SO4, filtered to form a residue which was purified by flash chromatography on silica gel (EtOAc/CH2Cl2: 20/80) to afford the title compound 43 (460 mg, 1.59 mmol, 36% yield).
