実験手順

A solution of the product of step i) (109 mg), tris(dibenzylideneacetone)dipalladium(0) (14 mg), azetidine-1-sulphonamide (145 mg), 2-dicyclohexyl-phosphino-2′,4′,6′-triisopropyl,1,1′-biphenyl (XPHOS) (14 mg) and cesium carbonate (120 mg) in anhydrous dioxane (2.3 ml) was heated at 100° C. for 45 min. The reaction mixture was partitioned between ethyl acetate and water. Acetic acid (0.2 ml) was added and the separated organic phase was washed with water and brine, dried (MgSO4) and the solvent evaporated under reduced pressure. The residue was purified by flash silica-gel chromatography eluting with 40% ethyl acetate in iso-hexane to give the sub-title compound as a yellow viscous oil. Yield: 78 mg.
