Methods of preparing N3-substituted-4-pyrimidones are disclosed. The methods include combining a 4-pyrimidone and a non-aqueous base, followed by an alkylating agent, for a time sufficient for the pyrimidone and the alkylating agent to react. Methods of preparing an N3-substituted-6-(substituted amino)uracil are also disclosed. The methods include (a) combining an N3-substituted-2-alkoxy-6-amino-4-pyrimidone with an amine compound selected from the group consisting of an amine salt and the corresponding free amine, to form a reaction mixture; and (b) heating the reaction mixture to at least 80°C for a time sufficient for the N3-substituted-2-alkoxy-6-amino-4-pyrimidone and the amine compound to react to form the final product.
