Participants

Reaction Steps

A solution of a 1.5 to 1 mixture of (E) and (Z) 3-(4-nitrophenylthio)-2-propenol (3.53 g, 16.71 mmol) (JCS, Perkin Trans. I, 1974, 25) in dichloromethane (40 mL) was treated with imidazole (2.28 g, 33.4 mmol) and TBDMSCl (2.77 g, 18.4 mmol), stirred at room temperature for 24 hours, and then partioned between dichloromethane and water. The organic phase was dried, concentrated, and purified on silica gel by flash column chromatography eluting with 8 to 1 hexanes/ethyl acetate to give 5.1 g (94%) of the desired product. Rf: 0.8 (2:1 hexane:ethyl acetate)
