Reaction Steps
A mixture of ethyl 2-(hydroxymethyl)acrylate (4.1 g, 32 mmol), pyrazole (2.6 g, 38 mmol) and potassium carbonate (11 g, 79 mmol) in acetonitrile (30 mL) was refluxed for 20 h, quenched by the addition of water (100 mL), and extracted with ethyl acetate (40 mL×2). The combined organic layers were washed with brine, dried over magnesium sulfate, and evaporated. The residue was purified by column chromatography on silica gel eluting with hexane/ethyl acetate (7/1) to afford 1.0 g (18%) of the title compound as a colorless oil:
