    Description / Table of Contents: Abstract Bromine reacts with 6-methyldihydropyrimidine-2-ones or 5-carbethoxy-6-methyldihydropyrimidine-2-ones to yield 6-bromomethyldihydropyrimidine-2-ones. 5-carbethoxy-6-bromomethyldihydropyrimidine-2-ones on heating split off ethyl bromide to give 6-hydroxymethyldihydropyrimidine-2-one-5-carboxylic acid lactones. Chlorine is added to the double bond of 5-carbethoxy-6-methyldihydropyrimidine-2-ones.
    Notes: Zusammenfassung Die Bromierung von 2-Oxo-6-methyl- bzw. 2-Oxo-5-carbäthoxy-6-methyltetrahydropyrimidinen verläuft unter Substitution an der CH3-Gruppe am C-6. 2-Oxo-5-carbäthoxy-6-brommethyl-bzw.-dibrommethyltetrahydropyrimidine können in 2-Oxo-6-hydroxymethyl-tetrahydropyrimidin-5-carbonsäurelactone umgewandelt werden. Im Gegensatz zu Brom reagiert Chlor mit 2-Oxo-5-carbäthoxy-6-methyltetrahydropyrimidinen unter Addition.
