Versuchsvorschrift

To a solution of 3-nitro-5-(trifluoromethyl)benzaldehyde (366 mg, 1.67 mmol) in MeOH (4 mL) was added a solution of 1-[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methanamine (270 mg, 0.84 mmol) in MeOH (4 mL) followed by addition of NaCNBH3 (105 mg, 1.67 mmol) and one drop of acetic acid. The reaction was stirred for 24 hours at room temperature and then poured into H2O (30 mL). The mixture was extracted with EtOAc (60 mL), and the organic extracts were washed with brine (20 mL), dried over Na2SO4, filtered, and concentrated. Purification by flash chromatography with 2% to 25% EtOAc/hexanes afforded {[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}[3-nitro-5-(trifluoromethyl)benzyl]amine as a yellow oil.
