실험 절차
436 Milligrams of ethyl 2-(4-tert-butoxycarbonylpiperazin-1-ylmethyl)-5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxylate as synthesized in Production Example 21 was suspended in 4 mL of 0.5N sodium hydroxide and stirred at 100° C. for 2 hours. After cooling off, the reaction liquid was neutralized with 1N hydrochloric acid, and the precipitate was recovered by filtration. Drying the same, 377 mg (92%) of the title compound was obtained.
