55% | In ethanol; | EXAMPLE A1 2-Bromo-acetoacetaldehyde (0.1 mol) was added portionwise to pyrazinamine (0.1 mol) in ethanol (200 ml) while stirring. The reaction mixture was stirred and refluxed for one hour, then allowed to cool to room temperature. The precipitate was filtered off and dried. Yield: 13.5 g of 1-(imidazo[1,2-a]pyrazin-3-yl)ethanone (55%) (interm. 1). |
