Procedure
A mixture of 6-(1-benzyl-3-methyl-1H-pyrazol-4-yl)-2-(pyrrolidin-2-yl)thieno[3,2-d]pyrimidin-4(3H)-one (391 mg) produced in Example 124, step C, ethyl 2-bromoacetate (184 mg), N-ethyl-N-(1-methylethyl)propan-2-amine (258 mg) and N,N-dimethylformamide (5 mL) was stirred at 60° C. for 2 hr. Ethyl acetate (50 mL) and water (50 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 residue was purified by basic silica gel column chromatography (ethyl acetate/hexane) to give the title compound (140 mg) as a colorless solid.
