Reaction Conditions

Reaction Steps

3-Chloro-5-fluorophenol (703 mg, 4.8 mmol) was added to a solution of potassium hydroxide (297 mg, 5.3 mmol) in H2O (1.45 mL) and heated at 60° C. Formaldehyde (37 wt % in H2O, 0.74 mL, 9.12 mmol) in H2O (1.45 mL) was added dropwise and the reaction mixture left to stir at 40° C. overnight. The reaction mixture was cooled to rt and conc. HCl (approximately 6 mL) was added. The resultant precipitate was filtered, washed with H2O and dried to yield the title compound as a cream solid (334 mg, 1.89 mmol).
