Versuchsvorschrift

To a solution of 2.41 g (10.0 mmol) of 5-(4-chlorobutylthio)imidazo[1,2-a]pyridine and 1.00 g (10.0 mmol) of hydantoin in 30 ml of N,N-dimethylformamide, 1.50 ml (10.0 mmol) of 1,8-diazabicyclo[5.4.0]-7-undecene was added, followed by stirring at 80° C. for 16 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/methanol=20/1→10/1) to yield 1.27 g (41.7%, yellow solid) of the desired product.
