Alkylation of 4,5,6-substituted 2-sulfanylpyrimidines with alkyl and benzyl iodides and chlorides gave the corresponding 2-alkylsulfanyl and 2-benzylsulfanyl derivatives. 2-Methylsulfanylpyrimidines reacted with morpholine, benzylamine, and 4-methoxyaniline in butanol to produce 2-amino derivatives.

Convenient synthesis of 2-(methylsulfonyl)pyrimidine derivatives
ABSTRACT An efficient and convenient approach for the preparation of functionalized 2-(methylsulfonyl)pyrimidine derivatives has been developed through cyclic condensation of malonate derivatives with S-methylisothiouronium sulfate followed by derivation and oxidation in water–acetone mixture using oxone as the oxidant. This synthetic strategy provides an efficient and environmentally friendly approach
