Methane → 2-Bromo-3,4-dichloroaniline

Participants

Reaction Steps

A solution of 2-bromo-3,4-dichloronitrobenzene (23.5 g) in toluene was treated at 25°-35° C. for 1.25 hours with hydrogen in the presence of charcoal containing 5% platinum. The solution was then filtered and the filtrate was evaporated to dryness. The brown solid thus obtained was dissolved in diethyl ether and the solution was treated with decolourising charcoal and filtered. Evaporation to dryness of the filtrate gave 2-bromo-3,4-dichloroaniline (18.0 g), m.p. 78°-80° C. in the form of a brown powder.
