実験手順

To a solution of tert-butyl (3S)-3-[6-(5-methyl-1H-pyrazol-4-yl)-4-oxo-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl]-2-azabicyclo[2.2.2]octane-2-carboxylate (143 mg) produced in Example 106, step B, in methanol (3.0 mL) was added 4M hydrochloric acid/ethyl acetate solution (1.0 mL) with stirring at room temperature. The reaction system was stirred with heating at 50° C. for 1 hr, and the precipitate was collected by filtration, and washed with ethyl acetate to give the title compound (128 mg) as a colorless solid.
