Synthetic Route of 70165-31-0, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 70165-31-0 as follows.
A tetrahydrofuran solution of a boranetetrahydrofuran complex (1 M; 50 mL) was added to a solution of 6-cyanonicotinic acid (0.85 g) in tetrahydrofuran (20 mL) under ice-water cooling, followed by stirring at room temperature overnight. Methanol was added to the mixture under ice-water cooling, and then a 10% hydrogen chloride in methanol was added to the mixture, followed by stirring for 1 hour at 40C at room temperature. The solvent was removed under reduced pressure, and the resultant residue was purified by means of silica gel column chromatography [Chromatorex NH] (eluent; methanol : methylene chloride=1 : 1) to prepare the titled compound (1.54 g, Example Intermediate 36-1).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,70165-31-0, its application will become more common.
