| titleOfInvention | Improved preparation of 1,2,5,6-tetrahydro-3-carboalkoxypyridines such as arecoline and salts of 1,2,5,6-tetrahydro-3-carboalkoxypyridines and arecoline hydrobromide |
| abstract | A process is provided for the preparation of 1,2,5,6-tetrahydro-3-carboalkoxypyridines of formula (III) wherein R is a straight or cyclic substituted or unsubstituted alkyl chain having 1 to 6 carbon atoms, phenyl C1-6 alkyl, menthol or a derivative of menthol, or a derivative of camphor, and R' is an alkyl chain having 1 to 4 carbon atoms or phenyl C1-6 alkyl comprising reacting an alkyl pyridinium salt of formula (II) wherein R and R' are as defined above and X is a suitable leaving group with sodium triacetoxyborohydride in the presence of an acid. |
