Reaction Steps

To a solution of 2-(4-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}-3,5-difluorophenyl)ethanol (3.1 g, 8.79 mmol) and cyanamide (0.443 g, 10.55 mmol) in anhydrous THF (20 mL) was added trifluoromethanesulfonic acid (1.873 mL, 21.10 mmol) at 0° C. The reaction mixture was stirred at 60° C. for 4 h. Purification via reverse phase Biotage then afforded the title compound as a white solid (1.5 g, 31.3% yield). LCMS: rt=3.64 min, [M+H+]=395
