An efficient and facile synthesis of thiosubstituted pyrimidine derivatives (4-amino-6-aryl-2-alkylthiopyrimidine-5-carbonitrile derivatives) by one-pot multicomponentreaction of aromatic aldehydes, malononitrile, and S-methylisothiouronium sulfate (or S-benzylisothiourea hydrochloride) in ethanolic NaOH is reported. Because of the simple work-up procedure, low cost, and, especially, high product
