ABSTRACT
In the present work, the new 3 [p-haloarylamino]4-methoxycarbonyl-5- aminopyrazole [3a-c] were obtained by using ketene S,S,acetal derivatives [1] as good precursors for the synthesis of p- haloarylaminomethoxycarbonyl methyl mercaptal [2a-c], which were prepared through displacement reaction of cyanomethoxycarbonyl ketene dithioacetal [1] with amines. The results of the study were given
