実験手順

After 680 mg (2.88 mmol) of methyl 6-oxo-1-(2-thiazolyl)-1,6-dihydro-3-pyridinecarboxylate was dissolved in 12 mL of methanol and 4 mL of water, 207 mg (8.64 mmol) of lithium hydroxide was added to the solution. Afterward, the resulting reaction solution was stirred at about 75° C. for 5 hours. After termination of the reaction was determined by liquid chromatography, the solvent was removed in vacuo, and aqueous HCl was then added to the reaction solution to titrate until pH 2 was reached. The resulting solid compound was filtrated to obtain a target compound (Actual yield: 466 mg, Percent yield: 73%).
