4,4-Dimethyl-7-nitro-3,4-dihydronaphthalen-1(2H)-one → 7-Amino-4,4-dimethyl-3,4-dihydronaphthalen-1(2H)-one

Participants

Reaction Steps

A solution of 230.0 mg (1.05 mmol) 3,4-dihydro-4,4-dimethyl-7-nitro-naphthalen-1(2H)-one (Compound D8) in 5.0 mL of EtOAc was stirred at room temperature with a catalytic amount of 10% Pd--C under 1 atm of H2 for 24 h. The catalyst was removed by filtration through a pad of Celite, and the filtrate concentrated under reduced pressure to give the title compound as a dark green oil.
