実験手順
671 Milligrams of ethyl 5-methyl-4-oxo-2-piperidinomethyl-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxylate was suspended in 8 mL of 0.5N sodium hydroxide, stirred at 80° C. for 2 hours, and allowed to cool off. The reaction liquid was neutralized with 2N hydrochloric acid, and the precipitate was recovered by filtration and dried, to provide 565 mg (92%) of the title compound.
