Reaction Steps
2-(3-Nitro-4-hydroxyphenyl) propionitrile (38.4 g., 0.2 mole.) was suspended in absolute ethanol (250 ml.) and hydrogenated at 4 atmospheres pressure and room temperature over 10% palladium on charcoal. Hydrogenation was complete in 3.8 hours. The catalyst was removed by filtration. Evaporation of the filtrate yielded 2-(3-amino-4-hydroxyphenyl) propionitrile (17 g.), m.p. 110° C.
