Procedure

Crude N-{[4-(Bromomethyl)phenyl] (methyl)oxido--sulfanylidene}-5-({3-[(3-methyl-2-furoyl)amino]phenyl}ethynyl)nicotinamide was dissolved in THF (2 mL). 2-(2-piperazin-1-yl-ethoxy)-ethanol (0.064 g, 0.390 mmol) and TEA (0.054 mL, 0.390 mmol) were then added to the solution and the resulting reaction mixture was allowed to stir for 1 h at rt. The reaction mixture, subsequently, was dissolved in EtOAc and then extracted with H2O (2× mL). The organic layer was dried over anhydrous Na2SO4(s), filtered and concentrated in vacuo. The crude product was purified via column chromatography (gradient eluant mixture of MeOH in EtOAc: 0% to 20% MeOH) to afford the title compound (0.064 g, 49% overall for step 1 and 2).
