Procedure
Bis(triphenylphosphine)palladium dichloride (0.005 g, 0.007 mmol) was added to a solution of 2-iodo-4H-1,3-thiazolo[5,4-c]isoquinolin-5-one (0.115 g, 0.35 mmol) and DMF (5 ml) at 23° C. After 30 minutes, tributylvinylstannane (0.11 ml, 0.37 mmol) was added, and the reaction mixture was stirred overnight at 45° C. All volatiles were evaporated, and the resulting oil was purified by flash-chromatography (CH2Cl2/methanol, 99/1) to afford the title compound as a yellow solid (a quantitative yield). m.p 235-239° C. (dec.); 1H NMR (200 MHz, DMSO) δ 5.55 (d, 1H, CHH, J=11 Hz), 5.95 (d, 1H, CHH, J=17 Hz), 6.85-7.00 (m, 1H, CH), 7.47-7.54 (m, 1H, Ar), 7.74-7.82 (m, 1H, Ar), 8.09-8.20 (m, 2H, Ar), 12.43 (bs, 1H, NH).
