To a solution of 2-(4-((5-chloro-6-(trifluoromethyl)pyridin-2-yl)oxy)phenyl)ethanol (0.2 g, 0.630 mmol) and cyanamide (0.053 g, 1.259 mmol) in dry THF (3 mL) under nitrogen was added triflic acid (0.112 mL, 1.259 mmol). The mixture was heated at 55° C. for 1 h. Purification via reverse phase flash chromatography afforded the title compound (250 mg, 0.529 mmol, 84% yield) as a white solid. LCMS: rt=2.77 min, [M+H+]=360
