Reaction Steps
cis-7-Methoxy-1-methyl-2-(n-propylamino) tetralin hydrochloride (100 mg, 0.37 mmol) was heated in 48% aqueous HBr for 3 h at 120° C. under N2. The volatiles were evaporated from the faint pink solution and the residue was treated twice with ethanol followed by evaporation, giving a faint pink residue which was dissolved in abs. ethanol. Dry abs. ethyl ether was added to the solution, yielding white crystals which were then recrystallized from MeOH-ethyl ether, yielding the desired product (75 mg, 70% yield), m.p. 262°-263° C.
