Reaction Steps

N-{3-[2-(Acetylamino)ethyl]-4-hydroxy-2,3-dihydro-1H-inden-5-yl}-3-phenylpropanamide (72.5 mg, 0.198 mmol) and pyridinium p-toluenesulfonate (12.4 mg, 0.0493 mmol) were heated under reflux in xylene (5 mL) for 2.5 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) and recrystallized (ethyl acetate/diisopropyl ether) to give the title compound (19.8 mg, yield 29%).
