Reaction Steps

cis-1-Ethyl-5-methoxy-2-(di-n-propylamino) tetralin hydrochloride (150 mg, 0.46 mmol) was heated in 48% aqueous HBr for 2 h at 120° C. under N2. The volatiles were evaporated in vacuo and the residue was crystallized from MeOH-ethyl ether. Two recrystallizations from MeOH-ethyl ether gave the desired product as HBr-salt (68 mg, 42%). Isomeric purity >95% (6C, 250° C.).
