Abstract
1,270,061. Preparation of 4-alkoxypiperidines. SIEGFRIED A.G. 5 June, 1970 [11 June, 1969], No. 27393/70. Heading C2C. 4-Alkoxypiperidines, which may contain one or more other ring substituents are made by hydrogenating the corresponding pyridines or N-oxides thereof in the presence of a catalyst comprising rhodium.
