Participants

Reaction Steps

A mixture of 1-(3-nitrophenyl)-1,4-dihydroisoquinol-3-one (12.2 g) and 5% palladium-carbon (3 g) in ethylacetate (400 ml) was hydrogenated at room temperature and pressure until uptake of hydrogen ceased. The mixture was filtered (celite), and the filtrate evaporated to dryness to give 1-(3-aminophenyl)-1,4-dihydroisoquinol-3-one (9.0 g), m.p. 179°-180° C. which was used without purification.
