Participants

Reaction Steps

To a solution of ethyl 2-[4-(3-{4-[4-(3,4-dichlorobenzoylamino)phenoxy]phenyl}propionyl)piperazin-1-yl]acetate (0.493° g, 0.843 mmol) in THF (5 mL) and ethanol (5 mL) were added 5 M aqueous sodium hydroxide (0.253 mL, 1.27 mmol) and water (1 mL), and the resulting solution was refluxed for 1 hour. This reaction solution was concentrated under reduced pressure, and the residue was dissolved in 50% aqueous ethanol. To the resulting solution was added 5 M hydrochloric acid (0.253 mL, 1.27 mmol), and the obtained solid was collected by filtration. To this solid was dissolved in ethanol (10 mL) and 5 M hydrochloric acid (0.3 mL) by heating. The solvent was then evaporated, and the obtained solid was recrystallized from ethanol-diethyl ether, to thereby yield 0.381 g of the title compound.
