実験手順

To a teflon-lined septum-sealed Schlenk tube, a mixture of Compound 1e (213 mg; 0.49 mmol), 2-methylsulfanyl-4-tributylstannanyl-pyrimidine (Compound 7a) (305 mg; 0.735 mmol) and tetrakis-(triphenylphosphine)palladium(0) (57 mg; 0.049 mmol) in dioxane (1.0 mL) was irradiated in a Microwave reactor at 150° C. for 30 min. The resultant mixture was diluted with EtOAc, and washed with saturated NH4Cl(aq) and H2O. The organic phase was washed with H2O, and then dried over Na2SO4. The mixture was filtered and the filtrate was evaporated under reduced pressure to give the crude material. The crude material was purified by flash column chromatography (SiO2), eluting with a heptane-EtOAc gradient to afford Compound 7b (129 mg; 50% yield). 1H-NMR (400 MHz, CDCl3): δ 8.48-8.50 (m, 1H), 8.08-8.12 (m, 1H), 7.54-7.57 (m, 1H), 7.16-7.23 (m, 2H), 6.96-7.01 (m, 2H), 6.27 (br. s, 0.7H), 5.18 (br, 0.3H), 4.25-4.36 (m, 1H), 3.88 (s, 3H), 3.24-3.59 (m, 4H), 2.68 (s, 3H), 1.79-2.16 (m, 4H), 1.44-1.54 (m, 9H); MS: m/z 525.2 (M+H)+.
