Reaction Steps

To a solution of 2-(4-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}phenyl)ethanol (2.63 g, 8.30 mmol) and cyanamide (0.419 g, 9.97 mmol) in dry THF (25 mL) under argon was added trifluoromethanesulfonic acid (0.885 mL, 9.97 mmol). The mixture was heated to 55° C. for 3 hrs. Purification via a reverse phase biotage with TFA then afforded the title compound (2.65 g, 62.8% yield). LCMS: rt=2.906 min, [M+H+]=359
