Reaction Steps
To a solution of 6.30 g (26.2 mmol) of 5-(4-chlorobutylthio)imidazo[1,2-a]pyridine and 3.64 g (26.2 mmol) of oxazolidine-2,4-dione potassium salt in 100 ml of N,N-dimethylformamide, 3.92 g (26.2 mmol) of sodium iodide was added, followed by stirring at 80° C. for 16 hours. After cooling, the reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with water and dried, after which the solvent was distilled off. The residue was purified by column chromatography (eluent: ethyl acetate) to yield 5.70 g (71.4%, light orange crystal) of the desired product.
