Procedure

To a dimethylformamide (0.6 mL) solution of 2-(4-Hydroxy-benzenesulfonyl)-6-oxa-2-aza-bicyclo[3.2.1]octan-7-one (101.1 mg) and cesium carbonate (331.3 mg) is added the aryl halide (2.5 equiv). The reaction is heated to 50° C. with shaking for 12-24 hours. The sample is cooled, diluted with water and ethyl acetate, and extracted two times with ethyl acetate. The organic layers are combined, dried over sodium sulfate and concentrated. The product is precipitated from diethyl ether to give the Aryloxy-benzenesulfonyl)-6-oxa-2-aza-bicyclo[3.2.1]octan-7-one.
