To a solution of 3-carboxylic acid p-nitrobenzyl ester (178 mg) in methylene chloride (4 ml) were added acetonitrile iodide (66 mg) and triethylamine (40 mg) under ice cooling, and the mixture was stirred for 30 minutes under ice cooling. Add methylene chloride (20ml) and water (20ml) and separate the organic layer.
After washing with water and drying, the solvent is distilled off. The residue was fractionated and purified using a silica gel Rover column (developing solvent: benzene: ethyl acetate = 15:1), yielding 89 mg of the target product.
