Synthetic Route of 504-29-0, 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 504-29-0, name is Pyridin-2-amine. This compound has unique chemical properties. The synthetic route is as follows.
Manufacturing Example 1-2-1: 2,2-Dimethyl-N-pyridin-2-yl-propionamide To a methylene chloride (500 mL) solution of 2-aminopyridine (50 g) were added triethylamine (81 mL) and pivaloyl chloride (72 mL) at 0C, which was stirred for 4 hours and 30 minutes at room temperature. Water was added to the reaction solution, and then extraction was performed with methylene chloride. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate and filtered, and then the filtrate was concentrated under a reduced pressure. Potassium carbonate (73 g) was added at 0C to a methanol (300 mL) solution of the residue thus obtained, which was stirred for 90 minutes at room temperature. Water was added to the reaction solution, and then extraction was performed with ethyl acetate. The organic layer was washed with saturated brine, then dried over anhydrous magnesium sulfate, and filtered, after which the filtrate was concentrated under a reduced pressure. Heptane (300 mL) was added to the residue, and the precipitated solids were filtered off to obtain the titled compound (80 g). The filtrate was then further concentrated under a reduced pressure, and the residue was purified by silica gel column chromatography (heptane:ethyl acetate = 2:1) to obtain the titled compound (12 g). 1H-NMR spectrum (DMSO-d6) delta (ppm): 1.22 (9H, s), 7.06-7.09 (1H, m), 7.72-7.77 (1 H, m), 8.01-8.03 (1 H, m), 8.29-8.31 (1 H, m), 9.71 (1 H, s).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 504-29-0, Pyridin-2-amine.
