Procedure

A mixture of 2-(1,4-dioxa-7-azaspiro[4.4]non-7-ylmethyl)-6-(5-methyl-1H-pyrazol-4-yl)thieno[3,2-d]pyrimidin-4(3H)-one (150 mg) produced in Example 39, step D, 6M hydrochloric acid (3 mL) and propan-2-ol (3 mL) was stirred with heating at 90° C. for 5 hr. Saturated aqueous sodium hydrogen carbonate (20 mL) was added to the reaction mixture, and the precipitated solid was collected by filtration, and washed successively with ethyl acetate (3 mL) and water (3 mL). The obtained pale-brown solid was crystallized from methanol/propan-2-ol/hexane to give the title compound (115 mg) as a pale-brown solid.
