Reaction Steps

To a CH3CN (2 mL) solution of amine (0.20 g, 0.58 mmol) from EX-601B was added 1,1,1-trifluoro-2,3-epoxypropane (0.10 mL, 1.2 mmol) and Yb(OTf)3 (0.035 g, 0.056 mmol). The cloudy solution was stiffed in a sealed flask at 40° C. After 18 h, additional 1,1,1-trifluoro-2,3-epoxypropane (0.20 mL, 2.4 mmol) and Yb(OTf)3 (0.035 g, 0.056 mmol) were added, and the mixture was heated an additional 4 h. diluted with diethyl ether and washed with water and brine. The organic layer was dried (MgSO4) and evaporated to an oil. Purification by flash chromatography on silica gel eluting with 10% ethyl acetate in hexane gave an oil which was dissolved in EtOH, stripped and dried in vacuo to give 0.14 g (53%) of the desired 3[(3-phenoxyphenyl) [[(3-(3-furanyl)phenyl]methyl]amino]-1,1,1-trifluoro-2-propanol product as a colorless oil, >99% pure by HPLC analysis.
