To a solution of 6-(3-chlorophenoxy)-1-methyl-2,4-dioxo-3-(3-(tetrahydro-2H-pyran-2-yloxy) propyl)-1,2,3,4-tetrahydrothieno[2,3-d]pyrimidine-5-carbaldehyde (65 mg, 0.136 mmol) in THF (2 mL) was added (3-chlorophenyl)magnesium bromide (35 mg, 0.163 mmol). The reaction was stirred at RT for 15 minutes then diluted with EA (20 mL) and water (20 mL). The organic layer was dried over Na2SO4 and concentrated to give a residue which was purified by chromatography eluted with PE/EA (4:1) to give 6-(3-chlorophenoxy)-5-((4-chlorophenyl) (hydroxy)methyl)-1-methyl-3-(3-(tetrahydro-2H-pyran-2-yloxy)propyl)thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (45 mg, 56.3% yield) as a yellow oil. LCMS: MH+ 591 and TR=2.138 min.
