実験手順

To a solution of the crude product of step 1 (0.75 g, 2.2 mmol) in DMF (10 ml) was added N-vinylacetamide (0.37 g, 4.36 mmol), triethylamine (243 mg, 0.33 ml, 2.40 mmol), palladium acetate (20 mg, 4 mol %) and bis(diphenylphosphino)propane (40 mg, 0.1 mmol). The reaction mixture was heated for 30 min at 130° C. using microwaves. The red solution was diluted and washed with hydrochloric acid (1M, 2×15 ml) and sodium hydrogen carbonate (saturated, 20 ml). The organic phase was dried over sodium sulphate and evaporated. Purification of the crude product by silica gel chromatography using ethyl acetate/n-heptane (2:1) gave the desired product.
