Sodium Azide → HCID 178510669, compound

Participants

Reaction Steps

A mixture of 2-benzenesulfonyl-3-(4-hydroxyphenyl)acrylonitrile (2.08 g, 7.3 mmol) and sodium azide (0.47 g, 7.3 mmol) in DMF (50 mL) was heated at reflux temperature 2 hours. After cooling, the mixture was poured on ice. The mixture was evaporated in vacuo to almost dryness and toluene was added. After filtration, the organic phase was evaporated in vacuo. The residue was purified by silicagel chromatography eluting with a mixture of ethyl acetate and heptane (1:2). This afforded 1.2 g (76%) of the title compound.
