실험 절차

A solution of 1,1,1-trifluoro-4-iodo-2-butanol (0.604 g, 2.38 mmol) in DMSO (4 mL) was treated with sodium azide (0.178 g, 2.74 mmol) at ambient temperature, followed by heating at 50° C. for 21 h. The mixture was diluted with cold water and extracted with ethyl acetate. The combined organic extracts were washed (brine), dried, and evaporated to give the product as a pale yellow oil (0.372 g, 92%).
