Reaction Steps

To a solution of 3-(5-(4-chlorobenzyl)-1-methyl-2,4-dioxo-6-(3-(trifluoromethoxy)phenoxy)-1,2-dihydrothieno[2,3-d]pyrimidin-3(4H)-yl)propyl 2,2,2-trifluoroacetate (25 mg, 0.039 mmol) in THF (4 mL) and water (4 mL) was added LiOH/H2O (3.29 mg, 0.079 mmol). The reaction was stirred at RT for 15 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 Prep HPLC to give 5-(4-chlorobenzyl)-3-(3-hydroxypropyl)-1-methyl-6-(3-(trifluoromethoxy)phenoxy)thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (10 mg, 47.1% yield) as a white solid. 1H NMR (DMSO-d6) δ: 7.49 (t, J=8.3 Hz, 1H), 7.21 (dd, J=18.8, 8.6 Hz, 4H), 7.17-7.07 (m, 2H), 7.03 (s, 1H), 4.50 (t, J=5.1 Hz, 1H), 4.10 (s, 2H), 3.99-3.86 (m, 2H), 3.51-3.42 (m, 2H), 3.41 (s, 3H), 1.69 (s, 2H). LCMS: MH+ 541 and TR=3.317 min.
