Allyl bromide → HCID 86749205, compound

Participants

Reaction Steps

A mixture of N-(3-hydroxy-1,2-benzisoxazol-5-yl)-1-cyclohexene-1,2-dicarboximide (0.75 g, 2.64 mmol), potassium carbonate (0.6 g, 4.35 mmol) and allyl bromide (1 g, 8.3 mmol) in N,N-dimethylformamide is heated at 60°-70° C. for 2 hours and diluted with water. The aqueous mixture is extracted with ether. The organic extracts are combined, washed sequentially with water and brine, dried over anhydrous sodium sulfate and concentrated in vacuo to obtain a yellow oil. Column chromatography of the oil using silica gel and ether/hexanes solutions yields a gum. A solution of the gum in an ether/hexanes mixture is passed through a plug of silica gel and crystallized to give the title product as a pale yellow solid, mp 88°-89° C.
