Participants

Reaction Steps

To 1-(1-benzyl-4-piperidinyl)-7-acetylaminocarbostyril (3.0 g) are added ethanol (32 ml) and an aqueous 10% sodium hydroxide solution (32 ml) and the mixture is refluxed for 1 hour. After the reaction mixture is concentrated by distilling off the solvent, water is added to the residue and the resulting solution is extracted with dichloromethane. The extract is concentrated by distilling off the solvent and recrystallized from ethanol/chloroform to give 1-(1-benzyl-4-piperidinyl)-7-aminocarbostyril (2.4 g) as white powders, m.p. 238°-241° C.
