  • Synthesis of anabaseine, salts and derivatives thereof
    Patent number: 5530134
    Abstract: A process for the synthesis of compounds of the formulas Ia and Ib below, wherein R.sub.1, R.sub.2, and R.sub.3, which are the same or different, are each selected from hydrogen and C.sub.1 -C.sub.4 alkyl, including the compound Anabaseine (Ia, wherein R.sub.1 =R.sub.2 R.sub.3 =H) (3,4,5,6-tetrahydro-2', 3'-bipyridine), the process comprising reacting sodium salt of .delta.-valerolactone with substituted ethyl nicotinate derivative to produce the Claisen product sodium 3-nicotinoyl-2-tetrahydropyranone enolate derivative, heating the sodium 3-nicotinoyl-2-tetrahydropyranone enolate derivative with concentrated HCl to produce 3-(5-chloro-1-pentanone-1-yl) pyridine derivative, dissolving the 3-(5-chloro-1-pentanone-1-yl) pyridine derivative in ethanol and then heating the 3-(5-chloro-1-pentanone-1-yl) pyridine derivative in ethanol with ethanolic ammonia solution in a sealed container to produce the compound Ia.
