Procedure

1-(1-(3-Chlorobenzyl)-7-methoxy-1,2,3,4-tetrahydronaphthalen-2-yl)pyrrolidine (6.6 g, 18.54 mmol) was dissolved in dichloromethane (100 mL). A 1 M solution of bortribromide in dichloromethane (55.6 mL, 55.6 mmol) was added dropwise under cooling maintaining the reaction mixture at room temperature. The reaction mixture was stirred at room temperature for 2 h. The reaction was poured on ice, made alkaline with sodium hydroxide. The aqueous phase was extracted with ethyl acetate and the combined organic extracts were washed successively with sodium bicarbonate and brine. The combined extracts were dried (MgSO4) and the solvent was evaporated in vacuo. The crude product (5.5 g) was used for the next step without further purification.
