Reaction Steps

A solution of stannous chloride dihydrate (50 g.) in concentrated hydrochloric acid (100 ml.) was stirred and heated at 60°-70° C. while 5-phenylseleno-2-nitroaniline (14.6 g.) was added in portions. The mixture was stirred at that temperature for 2 hours, and was then cooled and filtered. The solid product was stirred with concentrated sodium hydroxide solution and extracted with ether. The ether extract was separated and dried, and the solvent was evaporated to give the required starting material, 1,2-diamino-4-phenylselenobenzene as a yellow oil which slowly crystallised.
