실험 절차

Commercially available (S)-3-chloro-1-phenyl-1-propanol (6 g) was heated with excess sodium iodide (4 equiv., 18 g) and a few drops of triethylamine in 30 mL of methyl ethyl ketone at 100° C. for 20 h. A sample was taken and monitored by NMR to determine the extent of conversion. The solvent was removed in vacuo and the residue was taken up in dichloromethane and filtered to remove the salts and the iodoalcohol was purified by flash chromatography to yield 6.9 g of product.
