Reaction Steps

As described for example 320a, 4-methyl-2-pyrazolin-5-one was reacted with ethyl bromoacetate and potassium carbonate. Extractive workup followed by chromatography (SiO2, heptane:ethyl acetate=100:0 to 50:50) afforded the title compound as a white solid (yield: 16%). MS: m/e=185.0 [M+H]+.
