Versuchsvorschrift
To a solution of 100 mg (0.31 mmol) of 3-(4-chlorophenyl)-2(S)-(3-cyanophenyl)-1(S)-methyl-propylamine hydrochloride in 2 mL of CH2Cl2, 54 μL (0.31 mmol) of diisopropylethylamine and 62 mg (0.31 mmol) of 1-(4-chlorophenyl)-2-methyl-2-hydroxy-propan-1-one were added. After 5 min, 99 mg (0.47 mmol) of sodium triacetoxyborohydride was added and stirred for 3 hr. The reaction was quenched with water and the layers were separated. The organic layer was dried and concentrated. The residue was purified on a prep TLC plate using 30% EtOAc/hexane as an eluant to isolate two products. The higher Rf band gave 3-(1(S)-(4-chlorobenzyl)-2(S)-((2-hydroxy-2-methyl-1-phenylpropyl)amino)propyl)benzonitrile (diastereomer A) and the lower Rf band gave 3-(1(S)-4-chlorobenzyl)-2(S)-((2-hydroxy-2-methyl-1-phenylpropyl)amino)propyl)benzonitrile (diastereomer B). Diastereomer A, LC-MS: m/e=467 (M+1), 469 (M+3) (3.28 min). Diastereomer B, LC-MS: m/e=467 (M+1), 469 (M+3) (3.28 min).
