To a solution of 3-[3-chloro-5-(1-hydroxyethyl)-6-methoxy-2-methylphenyl]cyclobutanol (170 mg, 0.628 mmol) in dimethyl sulfoxide (1 mL) was added cyanuric chloride (64 mg, 0.34 mmol). After stirred overnight, the reaction mixture was diluted with ether and water. The aqueous layer was extracted with ethyl acetate once. The combined organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated. The crude was purified with silica gel column to give the desired product (39.6 mg, 22%). LCMS calculated for C14H18ClO2(M−Cl)+: m/z=253.1; Found: 253.2.
