PROCESS FOR PRODUCING CONDENSED CIS-TRIAZINE DERIVATIVES

A process for the preparation of condensed as-triazinium derivatives of the formula I (I) and isomers thereof, wherein R1 inter alia is an alkyl group, R2 inter alia is hydrogen or an alkyl group and R3 is hydrogen and where Z is a group of the formula a or b (a) (b) which comprises reacting a compo...

Summary:A process for the preparation of condensed as-triazinium derivatives of the formula I (I) and isomers thereof, wherein R1 inter alia is an alkyl group, R2 inter alia is hydrogen or an alkyl group and R3 is hydrogen and where Z is a group of the formula a or b (a) (b) which comprises reacting a compound of the formula II (II) where Y is a group of the formula c or d (c) (d) with a compound of the formula IIa NH2-CO-R2 (IIa) in the presence of a dehydrating agent. The advantage of the process is that it consists of fewer reaction steps and provides higher yields than the known methods. The compounds of formula I are pharmaceutically active known derivatives.
