실험 절차

A mixture of 0.16 g (0.468 mmole) of 6-[5-hydroxy-2-(2,2,2-trifluoroethoxy)benzamidomethyl]-2(1H)-pyridone, 0.05 g of 5% rhodium on alumina and 50 ml of methanol was hydrogenated on a Parr apparatus for 50 minutes. The mixture was filtered, the filtrate was evaporated, and the residue was dried to provide 5-hydroxy-N-(6-oxo-2-piperidylmethyl)-2-(2,2,2-trifluoroethoxy)benzamide. The structural assignment was confirmed by comparison of infrared and nuclear magnetic resonance spectra to those of the same compound prepared by an alternative synthetic procedure.
