반응 단계

To a solution of 6-bromo-5-(1-hydroxy-3-methylbutyl)-1-methyl-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (65 mg, 0.134 mmol) in dioxane (1 mL) was added (2-isopropylphenyl)boronic acid (88 mg, 0.536 mmol), Pd(dppf)Cl2 (10 mg) and aq. 2N K3PO4 (0.2 mL). The mixture was heated at 100° C. for 5 h, cooled to RT and filtered. The filtrate was concentrated and dried to a residue which was purified by chromatography eluted with PE/EA (10:1 to 6:1) to give 5-(1-hydroxy-3-methylbutyl)-6-(2-isopropylphenyl)-1-methyl-3-(3-((tetrahydro-2H-pyran-2-yl)oxy)propyl)pyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (30 mg, 42.7% yield) as a solid. LCMS: [M+-THP-OH] 423 and TR=2.047 min.
