100 °C

To a solution of 1 (0.300 g, 1.05 mmol) in DMSO (7 ml) were added 4-methoxyphenol (0.261 g, 2.1 mmol) and cesium carbonate (1.7 g, 5.25 mmol) and the suspension was shaken at 100° C. for 8 days. After cooling to r.t., the suspension was poured onto ice/water and the product was extracted with AcOEt. The organic phases were washed with water then brine, dried over MgSO4 and concentrated to dryness. The residue was triturated in hot EtOH then filtered off and dried under vacuum at 50° C. overnight, affording 202 mg (51%) of the title compound.
