Procedure

A mixture of ethyl {2-[6-(1-benzyl-3-methyl-1H-pyrazol-4-yl)-4-oxo-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl]pyrrolidin-1-yl}acetate (80 mg) produced in Example 152, step A, sodium borohydride (63 mg), tetrahydrofuran (5 mL) and ethanol (5 mL) was stirred at room temperature for 2 hr. 1M Hydrochloric acid (2 mL) was added to the reaction mixture under ice-cooling, and the mixture was neutralized with 1M aqueous sodium hydroxide solution (2 mL), ethyl acetate (20 mL) and water (20 mL) were added, and the separated aqueous layer was extracted with ethyl acetate (10 mL×2). The combined organic layers were washed with brine (20 mL) and dried over anhydrous magnesium sulfate. Insoluble material was removed by filtration, the filtrate was concentrated under reduced pressure and the mixture was crystallized from diethylether to give the title compound (73 mg) as a white powder.
