Procedure

The N-(3-phenoxyphenyl)-[[3-isopropoxyphenyl]methyl]amine (0.528 g, 1.59 mmol) product from EX-645B and 1,1,1-trifluoro-2,3-epoxypropane (0.506 g, 4.51 mmol) were heated to 90° C. in a sealed container for 2 d under an argon atmosphere. The resulting mixture was eluted from silica gel with an ethyl acetate in hexane gradient (0-10% ethyl acetate) and fractions were pooled after TLC analysis to give 197 mg (28%) of the desired 3-[(3-phenoxyphenyl)[[3-(isopro-poxy)phenyl]methyl]amino]-1,1,1-trifluoro-2-propanol product as clear, colorless oil. HRMS calcd. for C25H26F3NO3:446.1943 [M+H]+, found: 446.1936. 1H NMR (C6D6) δ 6.9-7.1 (m, 6H), 6.84 (tt, 1H), 6.74 (s, 1H), 6.66 (dd, 1H), 6.61 (d, 1H), 6.56 (t, 1H), 6.41 (td, 2H), 4.33 (s, 2H), 4.17 (septet, 1H), 3.91 (br s, 1H), 3.56 (dd, 1H), 3.31 (m, 1H,), 2.8 (br s, 1H). 1.06 (s, 6H). 19F NMR (C6D6) δ −78.85 (d, 3F).
