Abstract
Abstract Acylation of 2-aminobenzenethiol with methyl chloroformate in pyridine gave dimethyl 2, 2′-disulfanediylbis (2, 1-phenylene) dicarbamate instead of expected methyl 2- suylfanylphenylcarbamate. Heating of the product with zinc dust in glacial acetic acid led to the formation of 1, 3-benzothiazol-2 (3 H)-one. Alkylation of the latter with 1, 2- dibromoethane and allyl bromide, as well as acylation with chloroacetyl chloride, afforded ...
