Reaction conditions were found for the alkylation of tetrahydropyrimidine-2-thiones with ethyl chloroacetate, preventing a subsequent cyclization. Only one of the ester groups in the obtained alkylation products was subject to alkaline hydrolysis, while a treatment with ammonia in alcohol resulted in thiazolo[3,2‑a]pyrimidines.
