Participants

Reaction Steps

A solution of 6-(3-chlorophenyl)hexyn-1-ol (11.5 g, 55 mmol), triphenylphosphine (14.5 g, 55 mol) and phthalimide (8.1 g, 55 mol) in dry THF (110 ml) was treated with a solution of diethylazodicarboxylate (9.6 g, 55 mmol) in THF (20 mol) over several minutes. After 16 h, violates were removed in vacuo and the residue treated with ether. The precipitated solid was removed, the filtrate evaporated and the residue purified by flash chromatography on silica using dichloromethane as eluant. Evaporation of the appropriate fractions gave the product as a solid (16.5 g, 89%)
