Procedure

t-Butyl 4-nitrophenoxyacetate (19.3 g, 76.0 mmol) was dissolved in ethanol (100 ml) and 10% palladium-carbon (1.0 g) was added. The mixture was stirred at room temperature for 18 hours under a hydrogen atmosphere. The reaction mixture was filtrated and low boiling matters were distilled away from the filtrate under reduced pressure to give 16.8 g of t-butyl 4-aminophenoxyacetate as a pale-brown solid (99%).
