PURPOSE:To provide the subject new 1,2,5-thiadiazole derivatives useful as an organic intermediate or an intermediate for synthesis of a medical and agricultural drug and to provide a production method capable of synthesizing them from readily available raw materials in high yields and of readily and safely introducing an arbitrary substituent group. CONSTITUTION:3-R<2>-4-R<1>-1,2,5-thiadiazole derivatives [In the formula, R<1> is hydrogen atom, a 1-6C alkyl group (which may be substituted with fluorine atom or a 1-3C alkoxy group) or -C6H3XY (X and Y are same or mutually different and denote fluorine atom, chlorine atom, trifluoromethyl group, a 1-6C alkyl group or a 1-3C alkoxy group) and R<2> is a 1-6C alkyl group, provided that compounds in which R<1> and R<2> are respectively hydrogen atom or methyl group and methyl group are excluded]. |
