실험 절차

Under an inert atmosphere, 500 mg (1.57 mmol) of the compound obtained in Step C, 88 mg (78.9 μmol) of tetrakis(triphenylphosphine)palladium (0) and 155 mg (1.57 mmol) of potassium acetate in 15 ml of N,N-dimethylacetamide are heated at 160° C., for 2 hours. After returning to room temperature, the reaction mixture is filtered using a Büchner funnel and then evaporated to dryness. The residue is then hydrolysed and subsequently extracted with ethyl acetate. The organic phase is dried over magnesium sulphate, concentrated and purified by flash chromatography over silica gel (eluant:petroleum ether/ethyl acetate, 8:2) to yield the title compound in the form of a brown solid.
