The bromination of labeled acetophenone (I) with Br2 and AlCl3 gives phenacyl bromide (II), which is condensed with N-[2-(3,4-dimethoxyphenyl)ethyl]-N-methylamine (III), yielding the 2-aminoacetophenone (IV). The reduction of (IV) with NaBH4 affords the secondary alcohol (V), which is finally cyclized by means of H2SO4 and trifluoroacetic acid to provide the target 3-benzazepine.
