Vorschrift

To N-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenyl)acetamide in tetrahydrofuran (1.1 mL) cooled to −78° C. was added n-butyllithium (2.5 M, 0.13 mL). The reaction was stirred for 1 hour. 1-Isothiocyanato-3-methylbenzene was added and the solution was slowly warmed to 0° C. over 1 hour. The mixture was quenched with aqueous ammonium chloride and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, filtered, and concentrated. The residue was purified via radial chromatography using a 97:3 chloroform/methanol mixture as eluent providing the title compound as a tan solid (0.062 g, 55%).
