The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 97483-79-9, name is Ethyl 6-cyanopicolinate. This compound has unique chemical properties. The synthetic route is as follows. name: Ethyl 6-cyanopicolinate
To a 100-mL round bottom flask was added 40 mL of IN HC1 (aq). The flask was lowered into a 100C oil bath until the aqueous solution began to boil. While rapidly stirring, solid 6-cyanopicolinic acid ethyl ester (28.95 mmol, 5.10 g) was added to the boiling solution, and a vacuum adapter equipped with a glass frit was inserted into the top joint to limit the rate of water evaporation but allow for the removal of ethanol as the starting material was hydrolyzed. Because of the low melting point of the starting material, the reaction mixture was initially biphasic, but the biphasic mixture was slowly converted to a homogeneous solution as the starting material was consumed. The solution was stirred for one hour, and then the flask was removed from the oil bath and allowed to cool to room temperature under medium stirring to permit crystallization of the product. To complete crystallization, the mixture was stirred at 0C for another hour. The white precipitate was collected by suction filtration, washed with ice cold water (30 mL), followed by one portion (30 mL) of hot hexanes and one portion (30 mL) of 1 : 1 hexanes :dichlorome thane. The white solid was then recrystallized from boiling toluene, collected by vacuum filtration, and washed with additional toluene. Yield: 3.50 g (23.63 mmol, 82%).
