2) The chiral intermediates the amine (I) and the acid (II) have been obtained as follows: 2a) The bromination of 1-tetralone (IV) with Br2 in methanol gives the 2-bromotetralone (V), which is treated with hydroxylamine yielding the corresponding oximae (VI). The isomerization of (V) with polyphosphoric acid (PPA) at 80 C affords the benzazepinone (VII), which is treated with potassium phthalimide (VIII) in DMF to give the corresponding phthalimido derivative (IX). The reaction of (IX) with tert-butyl bromoacetate (X) by means of potassium tert-butoxide in DMF yields the benzazepinoacetic ester (XI), which is treated with hot ethanolamine to eliminate the phthalimido group yielding racemic (I). Finally, this racemate is submitted to optical resolution with L-(+)-tartaric acid to afford the chiral (S)-intermediate (I).
