実験手順
N-{3-[2-(Acetylamino)ethyl]-4-hydroxy-2,3-dihydro-1H-inden-5-yl}-4-(benzyloxy)pentanamide (210 mg, 0.495 mmol) and pyridinium p-toluenesulfonate (24.8 mg, 0.0991 mmol) were heated under reflux in xylene (10 mL) for 14 hr. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane=30/70→60/40) to give the title compound (162 mg, yield 81%).
