Reaction Steps
To a solution of (2R*,3R*)-3-[(2-benzyloxyethyl)amino]-2-[2,4-difluorophenyl]-1-(1H-1,2,4-triazol-1-yl)-2-butanol (4.40 g, 11.4 mmol) (obtained as described in reference example 2) in CH2Cl2 (40 mL) was added triethylamine (1.74 mL, 12.5 mmol). The resulting mixture was cooled in an ice bath and a solution of 4-(trifluoromethyl)benzoyl chloride (2.61 g, 12.5 mmol) in CH2Cl2 (5 mL) was carefully added and the mixture was stirred for 1 h at 0° C. and then for 18 h at room temperature. The resulting solution was diluted with CH2Cl2 and washed with 5% aqueous NaHCO3 solution. The organic phase was separated, dried over Na2SO4 and the solvent was removed, to afford a thick oil (9.17 g) that was purified by chromatography on silica gel (EtOAc: hexane 1:1). The title compound of the example was obtained as a white foam.
