Abstract Alkylation reactions of 2‐aminopyrimidine, 2‐aminothiazole, 2‐aminothiazoline, and their Cbz‐protected derivatives are described. Reactions with benzyl bromide proceed to give monoalkylated products with 2‐aminopyrimidine and 2‐aminothiazole, but 2‐aminothiazoline gives a dialkylated product. Reactions with xylylene dibromides are complicated by the tendency to form intramolecularly cyclized
