Participants

Reaction Steps

To a suspension of benzyl 4-(2-methoxy-2-oxoethoxy)benzoate (1.0 g, 3.33 mmol) in MeOH (15 mL) was added hydrazine hydrate (1.7 mL). After stirring for 1 h at rt, the reaction mixture was filtered. The cake was washed with MeOH (3×4 mL) and dryed under vacuo at 50° C. overnight gave 936 mg of the title compound (94%) as a white solid in 99.7% purity by HPLC (MaxPlot detection between 230 and 400 nm).
