Abstract

Functionally substituted novel triazaphenothiazines were sought for a study of their properties and reactions and for testing as antihypertensive and antipsychotic agents. The reaction of 2-amino-3-mercapto-6-picoline with 5, 6-disubstituted pyrimidines under acid- catalyzed conditions produced good yields of the new 1, 3, 9-triazaphenothiazine ring system. This heterocyclic ring is now the second known phenothiazine with three annular ...
