실험 절차

To a suspension of 1-[3-(7-Chloro-imidazo[1,2-a]pyridin-3-yl)-phenyl]-3-(2,2,2-trifluoro-ethyl)-urea (0.1 g, 0.27 mmol), tributyl-(1-ethoxy-vinyl)-stannane (0.091 ml, 0.27 mmol, 1 equiv), lithium chloride (0.034 g, 0.81 mmol, 3 equiv) in acetonitrile (4 ml) was added tetrakis(triphenylphosphine)palladium(0) (0.031 g, 27.2 μmol, 0.1 equiv). The reaction mixture was degassed by bubbling through N2, heated in the microwave at 150° C. for 20 min and filtered through a glass microfibre filter. To the filtrate was added 2N HCl (3 ml) and the mixture stirred vigorously for 2 h at room temperature, neutralised with saturated aqueous NaHCO3, extracted with CH2Cl2, the organics combined dried (MgSO4) and the solvent removed in vacuo. The residue was purified by preparative LC-MS to give the desired product as a yellow solid. MS: [M+H]+ 377
