Alkylation of the tetrahydropyrimidine derivatives with alkyl halides produces the 1,3-dialkyltetrahydropyrimidinium salts (4 and 5). The attempted dehydrogenation of 2 with sulfur leads to insertion of sulfur on the molecule.eninfo:eu-repo/semantics/closedAccessPhenylArticle45129362-s2.0-0001845269Q4WOS:A1997WJ19100006Q3
