It has been found that selective N1-alkylation of 3,4-dihydropyrimidine-2(1H)-ones can be achieved under solvent-less, mild phase transfer catalytic (PTC) conditions with tetrabutylammonium hydrogen sulfate and 50% aqueous NaOH as the catalyst and base, respectively. The procedure is tolerant to substitutional variation at key diversity points on the pyrimidinone moiety.
已发现，在无溶剂、温和的相转移催化（PTC）条件下，以硫酸氢四丁铵和50%的氢氧化钠水溶液分别作为催化剂和碱，可以实现3,4-二氢嘧啶-2(1H)-酮的选择性N1-烷基化。该方法对嘧啶酮部分关键多样性位点上的取代变化具有耐受性。
