Versuchsvorschrift

A solution of [3,5-bis(trifluoromethyl)benzyl]{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}amine (88 mg, 0.43 mmol) (Example 20) in 80% formic acid (3 mL) was heated to and maintained at reflux for 24 hours. The reaction was then cooled to room temperature, poured into saturated NaHCO3 (30 mL), and, after neutralization was complete, extracted with EtOAc (25 mL). The organic extracts were washed with brine (10 mL), dried over Na2SO4, filtered, and concentrated. Purification by flash chromatography with 15% EtOAc/hexanes afforded [3,5-bis(trifluoromethyl)benzyl]{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}formamide. Rf=0.20 (15% EtOAc/hexanes). LCMS=578.3 (M+1)+. 1H NMR (CD2Cl2, 600 MHz, rotamers present, ratio of major:minor ˜3:1. Data for major rotamer given.) δ 6.86-8.31 (m, 10H), 4.24-4.47 (m, 4H), 3.71 (s, 3H), 2.87 (m, 1H), 1.27 (m, 6H).
