PROCESS FOR PREPARING 2-SUBSTITUTED 4,6-DIALKOXYPYRIMIDINES

摘要

A process for the preparation of 2-substituted 4,6-diacoxypyrimidines of formula (I) from a cyanimidate of formula (II) which is cyclized with a hydrogen halide to form a halopyrimidine derivative of formula (III) which is converted to the final product of formula (I) by reaction with a compound of formula (IV) or an alkylamine of formula (V) .à
