実験手順

Methyl 5-(3-cyclopropylpropioloyl)thiophene-2-carboxylate (100 mg, 0.427 mmol) was dissolved in N,N-dimethylformamide (2 mL), and the solution was cooled to 0° C. Benzylhydrazine hydrochloride (74.5 mg, 0.470 mmol) was added followed by potassium carbonate (77 mg, 0.555 mmol). The mixture was stirred at 0° C. until the ice bath melted and was stirred overnight at room temperature. The solution was partitioned between water and ethyl acetate. The organic extract was dried with sodium sulfate, filtered, concentrated and purified by normal phase chromatography to afford the title compound.
