실험 절차

To a solution of methyl (4-cyanophenoxy)acetate (3.52 g, 18.4 mmol) in MEOH (100 mL) was added hydrazine hydrate (8.9 mL). After stirring for 1 h at rt, a solid precipitated out. Filtration, washing with MeOH (5 mL) and water (4×10 mL) and drying under vacuo at 50° C. overnight gave the title compound (2.63 g, 75%) as a white solid in 98.4% purity by HPLC (MaxPlot detection between 230 and 400 nm).
