A general, practical, and simple synthesis of functionalized 2-aminopyrimidines starting from β-chlorovinyl aldehydes and amidines is reported. In the presence of potassium carbonate, various ketones have been efficiently transformed into the pyrimidine derivatives by a two-step sequence involving the Vilsmeier–Haack reaction followed by a condensation reaction with guanidines. The protocol is distinguished by operational simplicity, inexpensive reagents, and functional-group tolerance. In many cases, pure solid products can be obtained in high to excellent yields without using column chromatography. The synthetic value of the method was demonstrated by the efficient synthesis of steroidal pyrimidines and a precursor of the antitumor agents Imatinib and Mocetinostat.
