Reaction Steps

The 4-amino-2-hydroxy-1,1,1-trifluorobutane (1.0 g, 7.0 mmol) from EX-611A and 3-(1,1,2,2-tetrafluoroethoxy)benzaldehyde (1.5 g, 7.0 mmol) were dissolved in 20 mL of dichloroethane and acetic acid (0.40 mL, 7.7 mmol), then solid NaBH(OAc)3 (1.8 g, 8.4 mmol) was added. The mixture was stirred at room temperature for 3 d, then quenched with water and extracted with ether. The ether layer was washed with water and brine, then dried over MgSO4, and evaporated to give 1.6 g of crude product, which was purified by reverse phase HPLC to give 0.90 g (37%) of the desired 4-[[[3-(1,1,2,2-tetrafluoroethoxy)phenyl]methyl]amino]-1,1,1-trifluoro-2-butanol product as a yellow oil. HRMS calcd. for C13H14F7NO2: 350.0991 [M+H]+, found: 350.0971.
