Procedure

To a solution of 3-(1-methyl-2,4-dioxo-6-(3-(trifluoromethyl)phenoxy)-5-((6-(trifluoromethyl)pyridin-3-yl)methyl)-1,2-dihydropyrido[2,3-d]pyrimidin-3(4H)-yl)propyl formate (35 mg, 0.060 mmol) in THF (4 mL) and water (4 mL) was added LiOH.H2O (5.04 mg, 0.12 mmol). The reaction was stirred for 15 min then diluted with EA (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 3-(3-hydroxypropyl)-1-methyl-6-(3-(trifluoromethyl)phenoxy)-5-((6-(trifluoromethyl)pyridin-3-yl)methyl)pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (13 mg, 39.0% yield) as a white solid. 1H NMR (DMSO-d6) δ: 8.63 (s, 1H), 8.51 (s, 1H), 7.75 (d, J=8.0 Hz, 1H), 7.62 (d, J=8.0 Hz, 1H), 7.51-7.49 (m, 1H), 7.36 (d, J=7.6 Hz, 1H), 7.23 (d, J=9.2 Hz, 1H), 6.98 (s, 1H), 4.78 (s, 2H), 4.50-4.48 (m, 1H), 4.00-3.96 (m, 2H), 3.61 (s, 3H), 3.48-3.43 (m, 2H), 1.75-1.71 (m, 2H). LCMS: MH+ 555 and TR=3.087 min.
