Procedure
To a solution of 2-{4-[(3-fluoro-4-methylphenyl)oxy]phenyl}ethanol (1 g, 4.06 mmol) and cyanamide (0.205 g, 4.87 mmol) in dry THF (15 mL) under nitrogen was added triflic acid (0.433 mL, 4.87 mmol). The mixture was heated at 55° C. for 2 h. Purification via reverse phase flash chromatography afforded the title compound (420 mg, 1.047 mmol, 25.8% yield) as white solid. LCMS: rt=2.61 min, [M+H+]=229
