The regioselective N1-alkylation of 3,4-dihydropyrimidin-2(1H)-ones via Mitsunobu reaction is reported. Using the highly reactive Mitsunobu coupling reagent combination N,N,N′,N′-tetramethylazodicarboxamide/tributylphosphine (TMAD-TBP) and a set of primary alcohols a small library of N1-alkylated dihydropyrimidones is obtained in good to excellent yields.
