Title: Imidazolinyl phenyl carbonyl compounds acid addition salts and related compounds
Abstract:This invention is concerned with tetrahydropyrimidinyl phenyl carbonyl acid addition salts, imidazolinyl phenyl carbonyl acid addition salts, dihydroimidazoisoindolols, tetrahydropyrimidoisoindolols, and tetrahydropyrimidoisoindolol acid addition salts which are all pharmacologically efficacious as anti-depressants. The tetrahydropyrimidinyl phenyl carbonyl acid addition salts, the tetrahydropyrimidoisoindolols and the tetrahydropyrimidoisoindolol acid addition salts are also efficacious as diuretics while the imidazolinyl phenyl carbonyl acid addition salts and the dihydroimidazoisoindolols are efficacious as anorexiants. This invention is also concerned with several processes for the preparation of these compounds.
Inventor(s): Sulkowski; Theodore S. (Wayne, PA)
Assignee: American Home Products Corporation (New York, NY)
Filing Date:Sep 06, 1973
Application Number:05/394,708
Claims:1. A process for the preparation of acid addition salts having the formula: ##SPC7##

wherein R.sub.1 is selected from the group consisting of hydrogen, lower alkyl, phen(lower)alkyl, phenyl, monohalophenyl, dihalophenyl, mono(lower)alkylphenyl, di(lower)alkylphenyl, trifluoromethylphenyl, mono(lower)alkoxyphenyl, di(lower)alkoxyphenyl, thienyl, pyridyl, furyl and tetrahydro-2-naphthyl; R.sub.2 is selected from the group consisting of hydrogen, halogen, amino, lower alkylamino, lower alkyl and lower alkoxy; R.sub.3 is hydroxy when R.sub.2 and R.sub.3 are dissimilar and when R.sub.2 and R.sub.3 are the same they are both selected from the group consisting of phenyl, monohalophenyl, dihalophenyl, mono(lower)alkylphenyl, di(lower)alkylphenyl, trifluoromethylphenyl, mono(lower)alkoxyphenyl, di(lower)alkoxyphenyl, thienyl, pyridyl, furyl and tetrahydro-2-naphthyl; n is 1; and HX is a pharmacologically acceptable acid, which comprises reacting a compound having the formula: ##SPC8##

wherein R.sub.1, R.sub.2, R.sub.3 and n are defined as above, with a pharmacologically acceptable acid in ethanolic solution.

2. A process according to claim 1 wherein the reaction occurs in an aqueous solution.
