To a solution of 1-methyl-2,4-dioxo-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)-6-(3-(trifluoro methoxy)phenoxy)-1,2,3,4-tetrahydrothieno[2,3-d]pyrimidine-5-carbaldehyde (50 mg, 0.095 mmol) in THF (2 mL) was added (4-chlorophenyl)magnesium bromide (0.19 mL, 0.190 mmol). The reaction was stirred for 2 min then diluted with DCM (5 mL) and water (5 mL). The organic layer was dried over Na2SO4 and concentrated to a residue which was purified by chromatography PE/EA (5:1 to 3:1) to give 5-((4-chlorophenyl)(hydroxy)methyl)-1-methyl-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)-6-(3-(trifluoromethoxy)phenoxy)thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (30 mg, 49.5% yield) as a solid. LCMS: [M+-THP-OH] 539 and TR=2.159 min.
