Facile N9-Alkylation of Xanthine Derivatives and Their Use as Precursors for <i>N</i>-Heterocyclic Carbene Complexes

Facile N9-Alkylation of Xanthine Derivatives and Their Use as Precursors for <i>N</i>-Heterocyclic Carbene Complexes

The xanthine-derivatives 1,3,7-trimethylxanthine, 1,3-dimethyl-7-benzylxanthine and 1,3-dimethyl-7-(4-chlorobenzyl)xanthine are readily ethylated at N9 using the cheap alkylating agents ethyl tosylate or diethyl sulfate. The resulting xanthinium tosylate or ethyl sulfate salts can be converted into...
