Versuchsvorschrift

To a solution of EXAMPLE 126B (1.14 g) and 1-(3-bromopropoxy)naphthalene (0.922 g) in N,N-dimethylformamide (20 ml) was added cesium carbonate (2.158 g). The reaction was stirred at room temperature overnight and diluted with ethyl acetate and washed with water. The organic layer was dried over sodium sulfate, filtered and concentrated. The residue was purified by flash chromatography, eluting with 0-50% dichloromethane in hexane to provide the title product.
