Reaktionsschritte

This entailed, in the first stage of the synthesis, absolute ethanol being saturated with ammonia at 0° C., and a solution of 2,4,6-trifluoropyrimidine (II) and ethanol then being added to the solution obtained in this way. It was possible, after elaborate separation of the isomers, to isolate 2-amino-4,6-difluoropyrimidine IVa' in 54.9% yield.
