反应详情

To a solution of 2-{4-[(4-fluorophenyl)oxy]phenyl}ethanol (750 mg, 3.23 mmol) and cyanamide (149 mg, 3.55 mmol) in THF (15 mL) was added trifluoromethanesulfonic acid (0.344 mL, 3.88 mmol) at 0° C. The reaction mixture was stirred at room temperature overnight. After removing the solvent, the residue was diluted with water, extracted with DCM. The organic phase was dried over sodium sulfate, filtered, and concentrated. Purification via reverse phase flash chromatography then afforded the title compound (290 mg, 1.057 mmol, 32.7% yield).
