Reaction Steps

In 30 ml of tetrahydrofuran and 130 ml of ethanol was dissolved 3.32 g of ethyl 3-hydroxy-4-nitrocinnamate. To the solution was added 100 mg of 10% palladium-carbon. The mixture was stirred under normal pressure in a hydrogen flow until absorption of hydrogen was discontinued. The catalyst was filtered off by suction and the filtrate was concentrated under reduced pressure to obtain 3.10 g of crude ethyl 4-amino-3-hydroxybenzenepropionate as an oily substance.
