Reaktionsschritte

To a cooled solution of phenol (149 mg, 1.58 mmol) in DMF (3.9 mL), NaH (60% in oil, 95 mg, 2.37 mmol) was added portionwise and the suspension was stirred at 0° C. for 15 min. 1-(Diphenylmethyl)azetidin-3-yl methanesulfonate (500 mg, 1.58 mmol; which may be prepared as described in Step 1) was then added and the reaction mixture stirred at 80° C. overnight and concentrated under reduced pressure. The residue was purified on column chromatography (eluent: pentane/EtOAc 98/2 to 95/5) to give the title compound (332 mg, 67%) as a light yellow solid.
