A simple, inexpensive, and green reaction permitting the synthesis of new C-6 arylsulfonylmethyl 4-aryl-3,4-dihydropyrimidinones in water by S-alkylation of 6-bromomethyl 3,4-dihydropyrimidinones 2 with benzenesulfinic acid anions 3 is reported. The required 6-bromomethyldihydropyrimidone precursors 2 were readily prepared using an organic solid brominating reagent.
