Reaction Steps

A solution containing 2-bromo-1-methoxyethyl-3,4-dichloroimidazole (2.74 g, 10 mmol), 2,6-diethylphenylboronic acid (2.14 g, 12 mmol.) and Pd(PPh3)4 (0.23 mg, 0.2 mmol) in toluene/2M Na2CO3 (30 ml/15 mL) in a sealed tube is degassed, then allowed to heat to 110° C. overnight. The organic layer is separated and concentrated in vacuo to dryness. The residue is purified by column chromatography on silica gel (hexane/ethyl acetate 100/5) to obtain the 2-(2,6-diethylphenyl)-1-methoxyethyl-3,4-dichloroimidazole. Synthesis of 2-(2,6-diethylphenyl)-1-methoxyethyl-4-chloro-imidazole-3-carboxaldehyde
