摘要：
Disclosed are a process and intermediates of the formulae ##STR1## wherein X.sup.- is halide, BF.sub.4.sup.-, R.sup.3 SO.sub.3.sup.-, wherein R.sup.3 is C.sub.1 -C.sub.6 alkyl, CF.sub.3, C.sub.1 -C.sub.6 alkylphenyl or phenyl, and Q is a group of the formula ##STR2## wherein R is C.sub.1 -C.sub.6 alkyl; useful for preparing benzazepine intermediates of the formula ##STR3## These benzazepine intermediates are useful for preparing benzazepines having activity as selective D1 receptor antagonists.
