A convenient method for the preparation of 4-amino-6-aryl-6H-pyrrolo[1,2-a][1]benzazepine-5-carbonitriles has been developed. The method is based on the hydrogen bromide-mediated cyclization reaction of 2-{aryl[2-(1H-pyrrol-1-yl)phenyl]methyl}propanedinitriles, produced by the treatment of 2-(1H-pyrrol-1-yl)phenyllithiums with arylidenemalononitriles. The lithium compounds can be easily generated by the bromine/lithium exchange between 1-(2-bromophenyl)-1H-pyrroles and butyllithium.

The present invention relates to the use of arylalkanolamine compounds with sigma-1 receptor antagonist activity. In particular, the said arylalkanolamine compounds are useful in the treatment of conditions selected from the abuse of psychotropic substances such as cocaine or amphetamines, pain and cancer.
