Reaction Steps

(E)-4-(4-(1H-1,2,4-triazol-1-yl)phenyl)-2-(3,5-dichlorophenyl)-1,1,1-trifluorobut-3-en-2-ol (DC69): To a solution of (E)-3-(4-(1H-1,2,4-triazol-1-yl)phenyl)-1-(3,5-dichlorophenyl)prop-2-en-1-one (1 g, 3 mmol) in THF (150 mL) was added trifluoromethyltrimethylsilane (0.517 g, 3.644 mmol) and tetra-n-butylammonium fluoride (TBAF) (1.0 M, 1 mL) at 0° C. The reaction was slowly warmed to ambient temperature and allowed to stir for 2 h. The reaction was then cooled to 0° C. and 5 M HCl solution was added and the reaction was stirred for an additional 4 h at ambient temperature. The reaction was extracted with CH2Cl2 and the combined organic layers were dried over Na2SO4 and concentrated under reduced pressure. The crude compound was purified by flash column chromatography (SiO2; 25% EtOAc/hexanes) to afford the title compound as an off-white solid (0.3 g, 25%).
