Participants

Conditions

Temperature: 60 °C

Procedure

To the solution of 2-(4-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}-3-fluorophenyl)ethanol (4.0 g, 11.95 mmol) and cyanamide (0.603 g, 14.34 mmol) in anhydrous THF (25 mL) was added trifluoromethanesulfonic acid (2.55 mL, 28.7 mmol) at 0° C. The reaction mixture was stirred at 60° C. for 4 h. Purification via a reverse phase Biotage then afforded the title compound as a white solid (1.5 g, 23.82% yield). LCMS: rt=3.68 min, [M+H+]=377
