6 N Hydrochloric acid (4 mL, 24.00 mmol) was added to a solution of ethyl 1-(2-tert-butoxy-2-oxoethyl)-3-methyl-1H-pyrazole-5-carboxylate (324 mg, 1.21 mmol) in THF (4 mL). The reaction mixture was stirred at room temperature overnight. The reaction mixture was extracted with ethyl acetate. The extract was washed with brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound (206 mg).
