Abstract:
THE PRESENT INVENTION IS CONCERNED WITH 2-(2-AMINOPHENYL)PHTHALIMIDINES AND 2-(2-AMINOPHENYL)ISOINDOLINES. THESE 2-(2-AMINOPHENYL)PHTHALIMIDINES ARE USEFUL INTERMEDIATES IN THE PREPARATION OF THEIR CORRESPONDING 2-(2-AMINOPHENYL)ISOINDOLINES WHICH ARE PHARMACOLOGICALLY EFFICACIOUS AS ANTI-CONVULSANTS.
Abstract:
Novel compounds have been prepared which have useful pharmacological activity as well as intermediates for their production. Some of the processes have utility for the production of other pharmacologically active compounds. The active compounds of this invention are those of the following formulas:
WHEREIN R1 is 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; R2 is selected from the group consisting of hydrogen, halogen, amino, (lower)alkylamino, (lower)alkyl and (lower) alkoxy; R3 is hydrogen when R2 and R3 are dissimilar and when R2 and R3 are the same they are both selected from the group consisting of hydrogen, halogen, (lower)alkyl and (lower)alkoxy; R4 and R5 are lower alkyl and attached to the same carbon atom; X is the anion portion of a pharmacologically acceptable acid-addition salt.
Abstract:
Novel 5,6-disubstituted-2,3,5,6-tetrahydroimidazo-(2,1- Alpha )isoquinolin-6-ols have been prepared which are useful antiinflammatory agents.
Abstract:
THIS INVENTION IS CONCERNED WITH TOLUIC ACIDS WHICH ARE USEFUL PRECURSORS IN THE PREPARATION OF 2-(AMINO(LOWER) ALKYL)PHTHALIMIDINES WHICH ARE UTILIZED AS INTERMEDIATES IN PREPARING 2-(AMINO(LOWER) ALKYL)ISOIDOLINES WHICH ARE PHARMACOLOGICALLY EFFICACIOUS AS ANTI-DEPRESSANTS AND ANOREXIANTS. THIS INVENTION IS ALSO CONCERNED WITH THE PROCESS OF PREPARING THESE TOLUIC ACID COMPOUNDS.
