Conditions

Temperature: 55 °C

Procedure

To a solution of 2-(3-fluoro-4-{[6-(trifluoromethyl)-2-pyridinyl]oxy}phenyl)ethanol (70 mg, 0.232 mmol) and cyanamide (11.72 mg, 0.279 mmol) in THF (5 mL) was added triflic acid (0.025 mL, 0.279 mmol) under argon. The mixture was heated at 55° C. for 3 h. Purification via reverse phase flash chromatography then afforded the title compound (50 mg, 0.102 mmol, 43.7% yield). LCMS: rt=2.53 min, [M+H+]=344
