Versuchsvorschrift
A mixture of 2-bromo-1-(thiazol-2-yl)ethanone (2.5 g; 12 mmol), acetonitrile (70 ml) and imidazole (1.65 g; 24 mmol) was stirred at ambient temperature for 1 hour. The mixture was evaporated to dryness and the residue partitioned between dichloromethane and water. The organic phase was separated, washed with saturated brine and evaporated to give 2-(imidazol-1-yl)-1-(thiazol-2-yl)-ethanone as a brown solid (1.17 g; 50%).
