With sodium acetate; In hexane; acetic acid; EXAMPLE 1 5-(3-Pyridyl)imidazo[1,2-a]pyrimidine A mixture of 5.29 g of <strong>[1450-93-7]2-aminoimidazole hemisulfate</strong>, 3.28 g of anhydrous sodium acetate and 7.04 g of 3-dimethylamino-1-(3-pyridyl)-2-propen-1-one (prepared according to the procedure of Example 1 in U.S. Pat. No. 4,281,000) in 100 ml of glacial acetic acid was heated under reflux for 16 hours. The solvent was removed in vacuo. The solid residue was made basic with saturated aqueous sodium bicarbonate, then was extracted with dichloromethane. The dichloromethane solution was passed through a short column of a hydrous magnesium silicate. The effluent was refluxed on a steam bath with the gradual addition of hexane until crystallization was noted. On cooling, the desired compound was separated and collected by filtration and gave 2.54 g of yellow prisms, mp 162°-164° C.
