Reaction Steps

6-bromo-2-methoxy-1-nitronaphthalene (12.6 g, 44.7 mmol), dimethylformamide (25.6 mL) and 7N NH3 solution in MeOH (128 mL, purchased from Sigma Aldrich) were combined in a Parr bomb. The bomb was heated in a lab oven at 130° C. After 48 hours, the reactor was removed from the oven and cooled to room temperature. The contents of the bomb were transferred to a glass round bottom flask. The bomb was thoroughly rinsed with dichloromethane and methanol, and the rinsings added to the flask. The contents of the flask were thoroughly concentrated on a rotary evaporator, leaving a brown solid. Water (200 mL) was added to the flask and the resulting suspension was agitated with a stir bar for 30 minutes. The resulting light brown powder was isolated by filtration, rinsing a few times with water. The filter cake was air dried over night to yield 6-bromo-1-nitronaphthalen-2-amine (11.6 g, >95% yield).
