(VIII).-A solution of 11 g. of VI1 in 50 ml. of absolute alcohol was shaken with hydrogen and 0.22 g. of Adams platinum oxide catalyst. The required amount of hydrogen was absorbed in about four hours. In this manner a total of 62 g. of VI1 was reduced. The combined alcohol solutions, after removal of the catalyst and evaporation of the solvent, left 58 g.(93%) of ethyl (l-benzoyl-3-ethyl-4-piperidyl)-cyanoacetate as a viscous pale yellow oil. A sample of this ...
