Reaction Steps

To the suspension of 4-benzyloxyaniline (10 g) in concentrated hydrogen chloride (100 ml) was added dropwise a solution of sodium nitrite (3.2 g) in water (10 ml) over 10min at between −15 and −10° C., and then the mixture was stirred at 3° C. for 1 hr. To the mixture was added dropwise a solution of tin chloride (33.5 g) in concentrated hydrogen chloride (80 ml) at between −20 and −10° C. over 30 min, and then the mixture stirred at 0° C. for 1 hr.
