실험 절차
Ethyl 2-morpholino-2-oxoacetate (1.0 g, 5.34 mmol) was dissolved in ethanol (7 mL) and hydrazine hydrate (0.267 g, 5.34 mmol) was added dropwise at 0° C. The reaction mixture was stirred at room temperature for 1.5 h. The reaction mixture was concentrated under reduced pressure to give 0.9 g of the crude product, which was used without further purification in the following step. Crude yield 90%. 1H NMR (400 MHz, CDCl3) δ 9.79 (s, 1H), 4.43-4.48 (m, 2H), 3.56-3.61 (m, 4H), 3.40-3.48 (m, 4H). LCMS m/z 174.16 [M+H]+, tR=2.031 min.
