Reaction Steps

1-(tert-Butyldimethylsilyloxy)-but-2-yn-4-ol (63, 4.0 g, 19.96 mmol), imidazole (1.80 g, 26.45 mmol), iodine (6.58 g, 25.95 mmol) and triphenylphosphine (6.80 g, 25.95 mmol) are treated in 100 ml dichloromethane according to J. Robertson et al. J. Chem. Soc., Perkin Trans. 1, 3389-3369, 2000. Work-up yields 4.42 g (71%) of a colourless oil. The product is used directly in the next step.
