Reaction Steps

To a solution of 2-(4-(4-chloro-2,6-difluorophenoxy)phenyl)ethanol (1.6 g, 5.62 mmol) and cyanamide (0.600 g, 14.27 mmol) in dry THF (10 mL) under nitrogen was added triflic acid (1.3 mL, 14.64 mmol) at 0° C. The mixture was stirred at room temperature for 2 h. Purification via reverse phase flash chromatography afforded the title compound (1.74 g, 3.65 mmol, 64.9% yield). LCMS: rt=2.66 min, [M+H+]=327
