Reaction Steps

A mixture of 7-[5-(1-allyl-1H-imidazol-2-yl)-4-(2,4-dichlorophenyl)-2-thienyl][1,3]thiazolo[5,4-d]pyrimidin-2-amine (28.0 mg, 0.058 mmol), acetic acid (2.0 mL) and DCM (6.0 mL) was degassed with vacuum and then the atmosphere was replaced with nitrogen. To the mixture, were added tetrakis(triphenylphosphine)palladium(0) (7.03 mg, 0.00608 mmol) and phenylsilane (0.10 mL, 0.81 mmol). The resulting mixture was stirred at 40° C. for 30 min. The mixture was allowed to cool to rt followed by adding sat. NaHCO3 and DCM. After being stirred for 10 min, the organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. Column chromatography was performed to yield the title compound (15.1 mg, 59%) as a pale yellow solid. LCMS: (AA) ES+445, 447. 1H NMR (400 MHz, d6-DMSO) δ: 11.82 (bs, 1H), 8.64 (s, 1H), 8.39-8.37 (m, 2H), 7.73 (d, J=2.0 Hz, 1H), 7.64-7.42 (m, 3H), 7.12 (bs, 1H), 6.95 (bs, 1H).
