実験手順

To a stirred solution of 133 (160 mg, 0.28 mmol) was added cerium(III)chloride heptahydrate (154 mg, 0.414 mmol) and sodium iodide (41 mg, 0.276 mmol) at room temperature (21° C.). The mixture was heated at 85° C. for 6 h. The solvent was evaporated and the residue was chromatographed using 0-15% methanol/dichloromethane gradient to give pure product 134 as a white solid (55 mg, 35% yield).
