Reaction Steps

Alternatively, 3-acetyl-8-methoxy-7-methylsulfonyl-2,3,4,5-tetrahydro-1H-3-benzazepine was treated with 3N hydrochloric acid to give 8-methoxy-7-methylsulfonyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrochloride, m.p. 228.5°-229.5°. Refluxing this compound with 48% hydrobromic acid gave 8-hydroxy-7-methylsulfonyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrobromide.
