4-Amino-2-methylthiopyrimidine derivatives (4) were synthesized by the cyclization of 3-cyano-2-methylisothiourea (2) with ketones (3).Oxidation of 4 produced 4-amino-2-methylsulfinyl or 2-methylsulfonylpyrimidine derivatives (7 or 8).Amination of 7 or 8 gave hypoglycemic 2-(1-piperazinyl)pyrimidines (1).Compounds 4 were converted to 4(3H)-pyrimidinone derivatives (12).Derivatives 1 were also synthesized via 12.Keywords - hypoglycemic drug; base-catalyzed cyclization; 3-cyano-2-methylisothiourea; 4-amino-2-methylthiopyrimidines; 4-amino-2-methylthio-5,6,7,8-tetrahydroquinazoline; 2-methylthio-4(3H)-pyrimidinones; 2-methylsulfinylpyrimidines amination; 2-methylsulfonylpyrimidines amination
