실험 절차
To a mixture of 6-bromo-1-methyl-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (See Compound 20, step 4, 200 mg, 0.50 mmol), CuI (28.7 mg, 0.15 mmol), Cs2CO3 (327.2 mg, 1.00 mmol) and 2-(dimethylamino)acetic acid (10.4 mg, 0.10 mmol) in dioxane (3 mL) was added 3-(trifluoromethyl)phenol (162.8 mg, 1.00 mmol). The reaction was heated at 140° C. (MW) for 2 h, cooled to RT then diluted with EA (15 mL) and water (10 mL). The organic layer was washed with water (20 mL) and brine (20 mL), dried over Na2SO4 and concentrated to a residue which was purified by chromatography eluted with PE/EA (10:1 to 1:1) to give 1-methyl-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)-6-(3-(trifluoromethyl)phenoxy)pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (150 mg, 62.3% yield) as a white solid. LCMS: [MH+-THP] 396 and TR=1.941 min.
