실험 절차

The title compound from example 17.1 (96 mg, 0.43 mmol), the title compound from example 34.1 (100 mg, 0.36 mmol) and cesium carbonate (419 mg, 1.29 mmol) were combined with a stir bar in a screw cap vial which was purged with nitrogen. The combined reagents were stirred in DMF and heated to 60° C. overnight. The reaction mixture was then diluted with water and extracted three times with chloroform. The organic phase was dried over magnesium sulfate, filtered and concentrated then chromatographed in 0-10% methanol in ethyl acetate (pale solid, 105 mg, 68%).
