Versuchsvorschrift

A solution of 3-(5-(4-(difluoromethoxy)phenyl)pyrimidin-2-ylamino)phenol 39 (1.2 mmol), 2-bromoethanol (1.4 mmol) and cesium carbonate (1.6 mmol) in acetonitrile (10 mL) is heated to 85° C. for 12 h then cooled to rt. The reaction is evaporated to dryness then re-dissolved in DCM. The organic mixture is washed with water and brine then dried over magnesium sulfate, filtered and reduced to dryness. Purification by silica gel chromatography with hexane:EtOAc=1:1 as eluant affords 2-(3-(5-(4-(difluoromethoxy)phenyl)pyrimidin-2-ylamino)phenoxy)ethanol 40a as white solid. MS (m/z) (M+1)+: 373.8.
