Procedure

To a solution of 6-bromo-1-methyl-2,4-dioxo-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)-1,2,3,4-tetrahydrothieno[2,3-d]pyrimidine-5-carbaldehyde (See Compound 2, Step 4, 185 mg, 0.428 mmol) in THF (5 mL) was added (4-chlorophenyl)magnesium bromide (0.77 mL, 0.772 mmol). The reaction was stirred for 5 min, diluted with water (10 mL) and extracted with DCM (3×10 mL). The combined organic layers were dried over Na2SO4 and concentrated to a residue which was purified by chromatography eluted with PE/EA (5:1 to 1:1) to give 6-bromo-5-((4-chlorophenyl) (hydroxy)methyl)-1-methyl-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (120 mg, 51.4% yield) as a solid. LCMS: [M+-THP-OH] 441 and TR=2.021 min.
