Phthalimide → HCID 69673484, compound

Participants

Reaction Steps

55 ml of toluene, 1.80 g of 2-vinyl-4-phenyl-3-butyn-ol, 1.93 g of phthalimide, and 3.45 g of triphenylphosphine were added to a nitrogen-substituted flask. Then, 5.30 g of diethyl azodicarboxylate (40% toluene solution) was slowly added dropwise to the above obtained solution under cooling on ice. The temperature was increased to a room temperature, and the obtained mixture was then stirred for 1 day. Thereafter, the reaction solution was concentrated, and 200 ml of diethyl ether was then added to the residue. The appearing solid was removed by filtration. The residue was concentrated, and it was then purified by flash chromatography (manufactured by Biotage AB; Isolera™), so as to obtain 1.00 g of 2-(2-vinyl-4-phenyl-3-butynyl)isoindol-1,3-dione.
