Procedure

Ethyl-2-(3-oxomorpholino)acetate (600 mg, 3.21 mmol) was dissolved in ethanol (3 mL) and hydrazine hydrate (160.46 mg, 3.21 mmol) was added at room temperature. The reaction mixture was heated at 80° C. for 1 h. The reaction mixture was transferred into 50 mL water and extracted with EtOAc (3×50 mL). The combined organic layers was washed with brine, dried over anhydrous sodium sulphate, and concentrated under reduced pressure to give the crude product, which was used without further purification in the subsequent step (Crude yield: 54%). LCMS m/z 174.05 [M+H]+ tR 2.489 min.
