4-Methoxy-1-methylpyrimidin-2(1H)-one is a heterocyclic organic compound characterized by a pyrimidine ring structure, which is a six-membered aromatic ring containing four carbon atoms and two nitrogen atoms. This specific compound features a methyl group (-CH3) attached to the first nitrogen atom and a methoxy group (-OCH3) attached to the fourth carbon atom. The numbering of the pyrimidine ring is such that the 2(1H)-one indicates a ketone functional group (C=O) at the second position, which is part of a six-membered ring and is protonated at the first position (1H), making it a tautomeric form. 4-methoxy-1-methylpyrimidin-2(1H)-one is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, particularly as a building block for the development of new drugs.

7152-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7152-66-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,5 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7152-66:
(6*7)+(5*1)+(4*5)+(3*2)+(2*6)+(1*6)=91
91 % 10 = 1
So 7152-66-1 is a valid CAS Registry Number.

HSAB-driven chemoselective N1-alkylation of pyrimidine bases and their 4-methoxy- or 4-acetylamino-derivatives

Gambacorta, Augusto,Tofani, Daniela,Loreto, Maria Antonietta,Gasperi, Tecla,Bernini, Roberta

, p. 6848 - 6854 (2007/10/03)

The lithium salts of the conjugated bases of 4-methoxy- and 4-acetylamino-2(1H)-pyrimidinones 1-3 undergo highly chemoselective N1-methylation or ethylation when treated with methyl- or ethylsulfate (hard electrophiles) in dry dioxane, while the use of DMF as solvent results in competitive O2-alkylation. Potassium salts of the same bases in DMF undergo prevalent O2-attack. Under the same conditions, a similar but less chemoselective behaviour is observed in alkylation of thymine and uracil, where some N3-attack occurs. This can be rationalised in terms of the HSAB principle.
