Reaction Steps

A solution of sodium nitrite (3.8 g, 0.055 mol in 20 mL of H2O), is added dropwise to an ice cold stirring suspension of 4-benzyloxyaniline (13.0 g, 0.055 mol in 150 mL of concentrated HCl). The reaction mixture is stirred for 90 minutes at -8° to 10° C. A solution of SnCl2.2H2O (32.0 g, 0142 mol in 50 mL concentrated HCl) is added and stirred for 1 hour at 0° C. The reaction mixture is removed from the ice bath and is stirred at room temperature for 20 hours. The mixture is then filtered and washed with water to give 13.0 g (95% yield) of product, m.p. 182°-185° C.
