실험 절차

At ambient temperature, 4.2 ml of 3M ethylmagnesium bromide are poured into 5.48 g of 4-iodo-1-trityl-1H-imidazole dissolved in 30 ml of dichloromethane. After 1 hour, 1 g of the product obtained in Step 1 is dissolved in 20 ml of dichloromethane. After hydrolysis with a saturated solution of ammonium chloride, extraction with dichloromethane, and then washing the organic phase with water, the solvent is evaporated off and the residue is purified by chromatography on silica gel, using as eluant a 98/2 dichloromethane/methanol mixture.
