  • Patent number: 6958400
    Abstract: Processes for preparing a 4-(secondary or tertiary)aminopyridine are provided. The processes comprise reacting a 4-substituted pyridine base having a leaving group as the 4-substituent, with an activating agent so as to form a corresponding 1,4-substituted pyridine; reacting the 1,4-substituted pyridine with a primary or secondary amine to substitute an amino group at the 4-position, and thereby form a corresponding 1-substituted-4-(secondary or tertiary) aminopyridine, wherein the reacting is conducted in a substitution reaction medium essentially free from strong base; and treating the 1-substituted-4-aminopyridine compound to remove the 1-substituent and thereby form a product medium including the 4-(secondary or tertiary) amino-pyridine.

  • Publication number: 20030232995
    Abstract: Described are preferred processes for producing extrusion-granulated supernucleophilic 4-amino-substituted pyridine catalysts, and granular products obtainable thereform. Also described are preferred activation-substitution-deactivation processes for producing 4-aminopyridine compounds, which involve the use of acrylic acid or acrylamide or analogs thereof for activation, and substitution steps conducted under mild basic conditions in an excess of the amine reagent for 4-substitution. Such processes provide improved reacted masses which are more readily processed to recover the products in pure, heat-stable form. Further, described are processes for preparing 4-substituted-pyridines via pyridine betaines.

  • Patent number: 6403825
    Abstract: Described are processes for producing citrate esters in, an economic fashion. Esters are prepared by esterification of a citric acid-containing fermentation broth having been treated to remove cations and optionally other impurities, but containing sugar(s). Esters are also prepared by reacting an impure aqueous citric acid source with an alcohol to provide a heterogeneous aqueous/organic reacted mixture, wherein the organic phase contains the ester and the aqueous phase retains water-soluble impurities. A liquid phase separation is then used to separate the organic and aqueous phases, conveniently separating the impurities from the product and avoiding the energy-intensive distillation of water from the reaction medium.
