Procedure

In a sealed tube, combine 2-bromo-thiazole (2.0 ml, 22.2 mmol), 3-hydroxy-benzaldehyde (1.8 g, 15.0 mmol) and potassium carbonate (2.1 g, 15.0 mmol) in dimethylformamide (20 ml). Heat to 100° C. After 48 hours, cool, pour into water (150 ml), and extract with ether. Combine the organic layers and wash sequentially with distilled water and brine and then dry (Na2SO4), filter, and concentrate to give a residue. Chromatograph the residue eluting with 9:1 hexane:EtOAc to give the title compound.
