    Abstract: A 1,2,4-thiadiazolidine-3,5-dione compound is provided to be used for synthesizing various 1,2,4-thiadiazolidine-3,5-dione compounds because of substitution of amide at 4-position of a thiadiazolidine-2,5-dione with a thiadiazolidine-3,5-dione as a skeleton. A 1,2,4-thiadiazolidine-3,5-dione compound is represented by a formula(1) and is prepared by hydrolyzing an ester compound represented by a formula(2) to prepare an acetic acid compound represented by a formula(3) and then reacting the compound of the formula(3) with an amine compound represented by a formula(4), wherein R1 is linear or branched saturated or unsaturated C1-7 alkyl, C1-7 alkoxycarbonyl C1-7 alkyl, phenyl, C1-7 alkyl substituted phenyl, benzyl or allyl; R1 and R2 are independent from each other and H, linear or branched saturated or unsaturated C1-7 alkyl, phenyl, halogen substituted phenyl, or R2 and R3 may form a ring, or the ring formed by an alkylene further includes 1-2 heteroatom(s) and may be further substituted by halogen, C1-7 alkyl, hydroxyl or C1-7 alkoxycarbonyl.
