Reaction Steps

A suspension of isopropyl 5-iodo-2-methoxybenzoate (1.52 g, 4.75 mmol), 4-cyclopropyl-1H-imidazole (0.777 g, 7.13 mmol), copper(I) oxide (0.067 g, 0.047 mmol), 8-hydroxyquinoline (0.103 g, 0.71 mmol), cesium carbonate (2.41 g, 7.41 mmol), PEG-3350 (1.18 g) and butyronitile (60 ml) was placed in a sealed tube, which was flushed with nitrogen and heated at 120° C. for 16 hours. The solvent was removed under reduced pressure, and the residue was purified by reversed phase HPLC to provide isopropyl 5-(4-cyclopropyl-1H-imidazol-1-yl)-2-methoxybenzoate. (0.720 g, 2.4 mmol). 51% yield. 301 (M+1).
