Reaction Steps

Bromoethane (0.75 g, 6.88 mmol) was added to a solution of 4,4-dimethyl-7-nitro-1,2,3,4-tetrahydroisoquinoline (1.4 g, 6.79 mmol) and K2CO3 (2 g, 14.47 mmol) in N,N-dimethylformamide (80 mL). The mixture was stirred at 50° C. for 4 hours. The solvent was removed under vacuum to give a residue which was purified by silica gel column chromatography eluting with 10% ethyl acetate/heptane to provide the title compound.
