実験手順

To a solution of 6-bromo-3-(3-hydroxypropyl)-1,5-dimethylthieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (50 mg, 0.15 mmol) in dioxane (2 mL) was added 3,4-dichlorophenylboronic acid (57.3 mg, 0.3 mmol), Pd(PPh3)4 (17.3 mg, 0.015 mmol) and aq. 2M K3PO4 (0.4 mL). The reaction was heated at 85° C. for 1 h, cooled to RT then diluted with EA (20 mL). The organic layer was washed with brine (20 mL) and aq. NH4Cl (20 mL), dried with Na2SO4 and concentrated to a residue which was purified by Prep HPLC to give 6-(3,4-dichlorophenyl)-3-(3-hydroxypropyl)-1,5-dimethylthieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (15.0 mg, 27.4% yield) as a white solid. 1H NMR (CDCl3) δ: 7.55-7.48 (m, 2H), 7.24 (d, J=2.1 Hz, 1H), 4.27-4.14 (m, 2H), 3.60-3.50 (m, 5H), 3.27 (t, J=6.5 Hz, 1H), 2.54 (s, 3H), 2.00-1.85 (m, 2H). LCMS: MH+ 399 and TR=3.000 min.
