For decades, the chemistry of heterocyclic compounds has been one of the most 
important sciences in organic synthesis and pharmaceutical chemistry. In addition, 
science and technology are moving to environmentally friendly and sustainable 
processes. In this context, multi-component reactions have become one of the main 
areas of synthetic organic chemistry. Compared to traditional methods, multicomponent 
reactions show higher efficiency and diversity because of their selectivity and economy 
of reaction steps, as well as the formation of carbon-carbon and carbon-heteroatom 
bonds in one pot, as evidenced by the simplicity of the process. will give. Usually, the 
purification of the products obtained as a result of multicomponent reactions is also 
simple, since all organic reagents participate in the reaction process and are used for the 
formation of the target products. 
As 
a 
continuation 
of 
the 
work, 
we 
dissolved 
homoveratrylamine,
p-hydroxybenzaldehyde and acetylaceto in ethyl alcohol in a magnetic stirrer. 
The progress of the reaction was monitored by thin-layer chromatography, and the 
hexahydropyrimidinone derivative was synthesized as a result of the reaction.
The structure of the product was established on the basis of IR and NMR 
spectroscopies.
