Participants

Reaction Steps

5-(2,3-epoxypropoxy)-8-phenylmethoxy-3,4-dihydrocarbostyril (130 mg) was dissolved in isopropanol (10 mL) and isobutyl 4-piperidylcarbamate (80 mg) was added. The mixture was then heated under reflux for 20 hours with stirring. After completion of the reaction, the isopropanol was evaporated under reduced pressure. The residue was then purified by flash chromatography (AcOEt/MeOH-99:1) to yield 160 mg of the title compound, 8-phenylmethoxy-3,4-dihydro-5-[2-hydroxy-3-(4-(isobutoxycarbonylamino)-1-piperidyl)propoxy]carbostyril.
