Participants

Reaction Steps

1-[1-(4-Nitrophenethyl)piperidin-4-yl]indoline (780 g) was dissolved in methanol (7 ml) and conc. hydrochloric acid (0.5 ml) was added dropwise into the resultant solution. Subsequently, the resultant mixture was catalytically reduced under atmospheric pressure in the presence of a palladium catalyst. After filtering off the catalyst, a 1 N aqueous solution of sodium hydroxide was added to the filtrate followed by extraction with chloroform. The organic layer was washed with brine and dried over magnesium sulfate. After evaporating the solvent, the title compound (620 mg) was obtained as an oil.
