Abstract:3-(Methylthio)benzenamine(1)was obtained from nitrobenzene through 5-step reactions including chlorosulfonation,reduction with KI/H3PO3,reduction with Na2S,methylation and reduction with Fe/HCl. The overall yield was 50.3%,and purity 99.1%(HPLC). The procedure developed had several advantages of facile reaction conditions,convenient operation and cheap reagents.
Key words:3-(methylthio)benzenamine; reduction; preparation; bis(3-nitrophenyl)disulfide
