Allyl bromide → HCID 20430390, compound

Participants

Reaction Steps

A mixture of 0.52 g. of 6-chloro-2,3,4,5-tetrahydro-1H-3-benzazepine, 0.34 g. of allyl bromide, 0.6 g. of potassium carbonate and 20 ml. of 90% ethanol was stirred at room temperature for 17 hours. The mixture was filtered and the filtrate concentrated in vacuo. The residue was extracted with 35 ml. of ether and the ethereal extract treated with isopropanolic hydrogen chloride to precipitate 3-allyl-6-chloro-2,3,4,5-tetra-hydro-1H-3-benzazepine hydrochloride. Recrystallization of this salt from absolute ethanol gave 3-allyl-6-chloro-2,3,4,5-tetrahydro-1H-3-benzazepine hydrochloride having a melting point of 248°-249°.
