Reaction Steps

To 4 g of 4-bromo-[1,1'-biphenyl]-3-amine were added 25 ml of water and 50 ml of concentrated HCl with stirring. The solution was cooled to 0° C. A solution of 1.1 g of sodium nitrite in 6 ml of water was then added dropwise while maintaining a temperature of 0° C. After this addition, the mixture was stirred at 0° C. for one hour. A solution of 20 g of stannous chloride in 20 ml of concentrated HCl cooled to -20° C. was added to the reaction mixture and again the mixture was stirred for one hour.
