Reaction Steps
Into a 100-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed 6,8-dichloro-2-methyl-4-(3-nitrophenyl)-1,2,3,4-tetrahydroisoquinoline (200 mg, 0.59 mmol, 1.00 equiv), Fe (360 mg, 6.43 mmol, 8.60 equiv), hydrogen chloride (0.02 mL), ethanol (0.6 mL), water (0.2 mL). The resulting solution was stirred for 0.5 h at 80° C. in an oil bath. The solids were filtered out. The resulting mixture was concentrated under vacuum. This resulted in 0.2 g (crude) of 3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenamine as yellow oil.
