2.44 G. of 1-amino-4-benzyloxy-2-nitrobenzene is stirred in 100 ml. methanol and 100 ml. 20% hydrochloric acid with 1.0 g. iron powder at room temperature. After 2 hours, the mixture is poured into excess ammonium hydroxide solution, the residue extracted with chloroform, filtered under nitrogen, dried over magnesium sulfate, filtered once again, and evaporated to dryness to give 1,2-diamino-4-benzyloxybenzene.
