Temperature: 80 °C

Procedure

To a stirring solution of 6-bromo-3-(difluoromethoxy)-2-methoxyphenol (200 mg, 0.743 mmol) in acetonitrile (10 mL) was added potassium carbonate (307 mg, 2.228 mmol) and 3-(bromomethyl)-3-(methoxymethyl)oxetane (288 mg, 1.48 mmol) and the resultant reaction mixture was heated to 80° C. for 16 h. The reaction mixture was cooled to RT, filtered through celite and the filtrate was concentrated under reduced pressure to afford 200 mg of 3-((6-Bromo-3-(difluoromethoxy)-2-methoxyphenoxy)methyl)-3-(methoxymethyl)oxetane as a solid.
