Tetrahydrofuran → HCID 69673265, compound

Participants

Reaction Steps

Under a nitrogen atmosphere, 9 ml of tetrahydrofuran, 1.02 g of the 2-benzyl-4-bromothiazole obtained in the above described stage, and 2.3 ml of triethylamine were added to 143 mg of dichlorobis(triphenylphosphine)palladium, 38 mg of copper iodide, and 0.80 g of N-(3-butynyl)phthalimide. The obtained mixture was stirred under reflux for 4 hours. After completion of the stirring, the reaction solution was cooled to a room temperature, and a solid was then filtrated. The filtrate was concentrated, and the residue was then purified by column chromatography (Wako Gel C-200; toluene:ethyl acetate=9:1), so as to obtain 1.00 g of a phthalimide compound.
