Versuchsvorschrift

To a solution of 3-(3-(tert-butyldimethylsilyloxy)propyl)-6-chloro-5-((4-chlorophenyl) (hydroxy)methyl)-1-methylpyrido[3,4-d]pyrimidine-2,4(1H,3H)-dione (100 mg, 0.19 mmol), 2-isopropyl phenylboronic acid (62.52 mg, 0.38 mmol), NaHCO3 (48 mg, 0.57 mmol), aq. 2M K3PO4 (0.47 ml, 0.94 mmol) in dioxane (1 mL) and water (0.2 mL) was added Pd(dppf)Cl2 (5 mg, 0.0068 mmol). The reaction was degassed with nitrogen (3×), heated at 120° C. (MW) for 1.5 h, cooled to RT then diluted with EA (10 mL) and water (2 mL) and filtered. The filtrate was concentrated to a residue which was purified by Prep TLC eluted with PE/EA (2:1) to give 3-(3-(tert-butyldimethylsilyloxy)propyl)-5-((4-chlorophenyl)(hydroxy)methyl)-6-(2-isopropylphenyl)-1-methylpyrido[3,4-d]pyrimidine-2,4(1H,3H)-dione (15 mg, 12.9% yield) as a colorless oil. LCMS: MH+ 608 and TR=2.668 min.
