Frass, Elzbieta et al. published their research in Roczniki Chemii in 1974 | CAS: 39083-15-3

5-Ethyl-6-methyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (cas: 39083-15-3) belongs to pyrimidine derivatives. Pyrimidines are isomeric with two other forms of diazines: pyridazine, with the nitrogen atoms in the 1 and 2 positions; and pyrazine, with the nitrogen atoms in the 1 and 4 positions. Pyrimidine derivatives also play an important role in drug development, either in concert with other compounds or on their own.Synthetic Route of C7H10N2OS

Alkylated derivatives of uracil. VI. Synthesis and properties of 5,6-oligomethyleneuracils was written by Frass, Elzbieta;Draminski, Marcin;Fiszer, Bernard. And the article was included in Roczniki Chemii in 1974.Synthetic Route of C7H10N2OS The following contents are mentioned in the article:

Reaction of β-keto esters and thiourea gave I (n = 1, 2, 3; X = S) and II (R = Me, Et; R1 = Me, Et, Pr; X = S) I (X = S) were converted to I (X = O) by heating with 10% ClCH2CO2H. Irradiation of I and II with a low pressure lamp gave only 10% yields of products. This study involved multiple reactions and reactants, such as 5-Ethyl-6-methyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (cas: 39083-15-3Synthetic Route of C7H10N2OS).
