Reaction Steps

To a solution of 2-(4-{[3-chloro-5-(trifluoromethyl)phenyl]oxy}phenyl)ethanol (2 g, 6.32 mmol) and cyanamide (0.4 g, 9.51 mmol) in dry THF (20 mL) under nitrogen was added triflic acid (0.8 mL, 9.01 mmol). The mixture was heated at 55° C. for 4 h. Purification via reverse phase flash chromatography afforded the title compound (2.1 g, 4.45 mmol, 70.5% yield) as a brown oil. LCMS: rt=2.95 min, [M+H+]=359
