실험 절차

To a solution of methyl 5-acetoxy-2-formyl-4-methoxyhydrocinnamate (3.31 g) and imidazole (2.42 g) in methylene chloride (25 ml) is added a solution of tert-butylchlorodimethylsilane (2.73 g) in methylene chloride (25 ml). The mixture is stirred at room temperature for about 60 minutes, diluted with ether and water, and the organic layer washed with water, brine, dried over magnesium sulfate, filtered and concentrated in vacuo to give the desired product.
