A process for the preparation of condensed as-triazinium derivatives of the formula I ##STR1## and isomers thereof, wherein R.sub.1 inter alia is an alkyl group, R.sub.2 inter alia is hydrogen or an alkyl group and R.sub.3 is hydrogen and where Z is a group of the formula a or b ##STR2## which comprises reacting a compound of the formula II ##STR3## where Y is a group of the formula c or d ##STR4## with a compound of the formula IIa

Process for the preparation of condensed as-triazine derivatives

The invention relates to new compounds of the general Formula I ##STR1## and isomers thereof wherein R.sub.1 is C.sub.1-10 alkyl, C.sub.3-6 cycloalkyl or phenyl, naphthyl or phenyl-(C.sub.1-4 alkyl), wherein the aryl ring of the three latter groups may optionally bear one or more halogen, nitro, trifluoromethyl, amino, hydroxy, C.sub.1-4 alkyl and/or C.sub.1-4 alkoxy substituent(s);

Condensed as-triazine derivatives

The invention relates to selected stereoisomers having the E, E or E, Z configuration and within the Formula (I) ##STR1## wherein N is 2-4, A is alkylene or 2 or 3 carbon atoms, R is phenyl or substituted phenyl and R.sup.1 and R.sup.2 are lower alkyl, or, together with the carbon to which attached, form a heterocyclic ring; and pharmaceutically acceptable acid addition salts thereof, a process for their preparation and pharmaceutical compositions comprising the same. The compounds of the general formula (I) can be used in therapy due to their narcosis potentiating, analgesic and antiarrhythmial effect.
