Process for the preparation of hydrogen halides of ethyl 1-methyl-4-phenyl-4-piperidinecarboxylate and intermediates for its implementation |
| abstract |
A method for the preparation of hydrogen chloride is described. of 1-methyl-4-phenyl-4-piperidinecarboxylic acid ethyl ester of the general formula (I) wherein X is chloro or bromo, consisting of the catalytic debenzylation of quaternary piperidinium salts of 1-benzyl-1-methyl-4-ethoxycarbonyl-4 -phenyl-1-methylpiperidinium chloride, respectively. with hydrogen on the Pd catalyst in a polar protic solvent at 20 ° C to the boiling point of the solvent. |
