実験手順
A 1M solution of BBr3(2.56 mL, 2.56 mmol) in CH2Cl2 was added to 3-ethyl-3-(3-methoxy-phenyl)-azepane (as described in Example 8, Step A) (0.300 g, 0.1.28 mmol) dissolved in anhydrous CH2Cl2 (10 mL) at −78° C. After 20 h of stirring at room temperature, the reaction was quenched with sat. NaHCO3 solution, extracted with CH2Cl2 (3×), dried (MgSO4) and concentrated to give the title compound.
