The invention relates to a 1,3,4-thiadiazole benzisothiazolinone acetamide derivative and a synthesis method thereof. The 1,3,4-thiadiazole benzisothiazolinone acetamide derivative has a structural formula shown in a drawing, wherein R is hydrogen, 3-methyl, 4-methoxy, 4-chloro or 2-bromo-4-nitro. The synthesis method comprises the steps of dissolving substituted 2-amino-5-substituted phenyl-1,3,4-thiadiazole and benzisothiazolin-3-one-2-yl acetic acid with an organic solvent, adding a condensing agent, reacting for 16-24 hours at the temperature of 10-30 DEG C, pouring a solution into water after the reaction is completed, and precipitating solids; filtrating, washing, drying, and then carrying out column chromatography, thereby obtaining the 1,3,4-thiadiazole benzisothiazolinone acetamide derivative which has good biological activity. According to the 1,3,4-thiadiazole benzisothiazolinone acetamide derivative and the synthesis method thereof, the reaction conditions are mild, the reacting operation is simple and convenient, and the reaction yield is relatively high.
