Versuchsvorschrift

0.26 ml of acetyl chloride is added to a mixture of 0.98 g of 1-(5-amino-2-pyridyl)-2-(2-(dimethylamino)benzylthio)imidazole, 1 ml of triethylamine and 30 ml of methylene chloride under ice-cooling. The mixture is stirred at the same temperature for 2 hours, washed with water and a saturated aqueous sodium bicarbonate solution, dried and evaporated to remove the solvent. The residue is purified by silica gel column chromatography solvent; chloroform:methanol=30:1), and crystallized with isopropyl ether. The crystals are collected by filtration, whereby 0.82 g of 1-(5-acetylamino-2-pyridyl)-2-[2-(dimethylamino)benzylthio]imidazole is obtained.
