Condensation of various amines (Ia–c) with 4-isothiocyanato-4-methyl-2-pentanone (2a) at room temperature gave tetrahydropyrimidinethiones (3a–c) whereas condensation of 1a–e with 3-isothiocyanatobutanal at room temperature gave tetrahydropyrimidinethiones (4a–e). Amines 1a, d, f–i on condensation with 4-isothiocyanato-4-methyl-2-pentanone (2a) by heating under reflux for 8 h at pH ~4 (for 1a, d) and
