Reference of 167837-43-6, 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 167837-43-6, name is (E)-3-(6-Aminopyridin-3-yl)acrylic acid. This compound has unique chemical properties. The synthetic route is as follows.
EDC hydrochloride (118 mg, 0.62 mmol) was added to a solution of methyl- thieno [3,2-c] PYRIDINE-2-YLMETHYL-AMINE (100 mg, 0.56 mmol), (E)-3-(6-AMINO-PYRIDIN-3- yl) acrylic acid (101 mg, 0.62 mmol), HOBT H2O (83 mg, 0.62 mmol) and triethylamine (235 FL, 1.68 mmol) in anhydrous DMF (5 mL). The mixture was stirred at room temperature overnight then diluted with H20 (10 mL) and extracted with CH2C12 (3 x 50 mL). The combined organic fractions were dried over MGS04, filtered and evaporated to give a yellow residue which was subjected to flash chromatography on silica gel (10% MeOH : CH2C12) to yield the title compound (61. 0%).’H-NMR (300 MHz, CDC13) 6 9.04 (s, 1H), 8.45 (d, J= 5.3Hz, 1H), 8.26 (s, 1H), 7.76-7. 67 (m, 3H), 7.32 (d, J= 15. 0Hz, 1H), 6.76 (d, J= 15.2 Hz, 1H), 6.53 (d, J= 8.3 Hz, 1H), 4.95 (s, 2H), 4.76 (br s, 2H), 3.22 (s, 3H); MS (ES) m/e 325.1 (M+H) +.
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 167837-43-6, (E)-3-(6-Aminopyridin-3-yl)acrylic acid.
