| titleOfInvention | Process for preparing piperidine derivatives |
| abstract | 1390252 Piperidine compounds; borates SANKYO CO Ltd 31 Jan 1972 [29 Jan 1971] 27221/74 Divided out of 1390251 Headings C2B C2C and C2P [Also in Division C3] Piperidine compounds of general Formula I wherein R<SP>1</SP> and R<SP>2</SP> may be the same or different, and each represents an alkyl group having from 1 to 4 carbon atoms; or R<SP>1</SP> and R<SP>2</SP>, together with the carbon atom to which they are attached, constitute a saturated alicyclic group or a group of the formula X represents a hydrogen atom, an oxygen free radical, or an alkyl group having from 1 to 4 carbon atoms; = 1, 2, 3 or 4; and when n = 1 R 3 represents an acyl group derived from an aliphatic or aromatic monocarboxylic acid; when n =2 R<SP>3</SP> represents a diacyl group derived from an aliphatic or aromatic dicarboxylic acid, or a carbonyl group; when n = 3 R<SP>3</SP> represents a triacyl group derived from an aliphatic or aromatic tricarboxylic acid, or a trivalent group derived by removal of three hydroxyl groups from phosphoric acid, phosphorous acid or boric acid; and when n =4 R<SP>3</SP> represents a tetraacyl group derived from an aromatic tetracarboxylic acid, or a tetravalent group derived by removal of four hydroxyl groups from orthosilicic acid; or a salt thereof, are prepared by reacting a 4- piperidinol derivative of formula with an ester of formula in the presence of an alcoholysis catalyst (wherein R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>, X and n have the meanings already given, and R<SP>4</SP> represents C 1 -C 3 alkyl) and, if appropriate, salifying the reaction product. |
