実験手順

To a solution of 241 mg (1.0 mmol) of 5-(4-chlorobutylthio)imidazo[1,2-a]pyridine and 227 mg (1.0 mmol) of 5-(1-methylpiperazin-4-yl)methylene-thiazolidine-2,4-dione in 10 ml of N,N-dimethylformamide, 0.15 ml (1.0 mmol) of 1,8-diazabicyclo[5.4.0]-7-undecene was added, followed by stirring at 80° C. for 3 hours. After the reaction mixture was cooled, water was added; the mixture was extracted with ethyl acetate and dried, after which the solvent was distilled off. The residue was purified by column chromatography (eluent, chloroform/ethanol=50/1) to yield 330 mg (76.0%, light yellow oily substance) of the desired product.
