To a solution of 43 (400 mg, 1.19 mmol) in CH2Cl2 (5 mL) was added TFA (5 mL). The reaction mixture was stirred for 2 h before being concentrated. The residue was subjected to reverse phase column chromatography (CH3CN/H2O/0.1% Formic acid=5% to 100%) to give 1-((S)-4-(3,4-dichlorophenyl)-3,4-dihydronaphthalen-2-yl)ethanamine (0.31 g, 77.5%) as a mixture of two diastereomers (45 and 46).
