苯甲醯丙酮、醛及尿素能順利地縮合成2-酮-4-R-5-乙醯基(或苯甲醯基)-6-苯基(或甲基)-1,2,3,4-四氫化嘧啶。此反應用鹽酸為催化劑。

The condensation of benzoylacetone, aldehyde and urea proceeded smoo:hly according to the course of Biginelli reaction, which was accelerated by hydrochloric acid. The various 2-keto-1,2,3,4-tetrahydro-pyrimidines formed in this reaction should be represented by either of the following two formuhdons.
