Title compds. (I; R,R1 = -COR4, -C=N-COOR5(NHCOR6); R4 = H, alkyl, cycloalkyl, amino and alkoxy; R5 = alkyl, alkenyl, alkinyl; R6 = H, alkyl, cycloalkyl, alkenyloxy, aralkyl and alkenyl; R2, R3 = H, C1-4 alkoxy, halogen, trifluoromethyl, and C1-4 alkyl; X = -O-SO2, -SO2-O; R7 = C1-4 alkyl), useful as parasiticides, were manufd. by reaction of II and III. Thus, 2-amino-4-phenoxysulfonyl-acetanilide refluxed with N,N'-bis-methoxy-carbonylisothio-urea-S-methylether and mixed with ethylacetate to give N-(2-acetamino-5-phenoxy-sulfonylphenyl)-N',N"-bis-methoxycarbony1-guanidine.
