実験手順

To a mixture of 6-hydroxy-1-methyl-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (See Compound 36, step 2, 500 mg, 1.49 mmol), CuI (85.2 mg, 0.45 mmol), Cs2CO3 (971.6 mg, 2.98 mmol) and 2-(dimethylamino)acetic acid (76.87 mg, 0.75 mmol) in dioxane (20 mL) was added 3-bromopyridine (588.9 mg, 3.73 mmol). The reaction was heated at 135° C. for 5 h followed by heating at 100° C. for 18 h, cooled to RT then diluted with EA (25 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-6-(pyridin-3-yloxy)-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (450 mg, 73.2% yield) as a yellow oil. LCMS: [MH+-THP] 329 and TR=1.065 min.
