Reference of 179687-79-7, 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 179687-79-7, name is 2-((2-Chloro-4-nitrophenoxy)methyl)pyridine. This compound has unique chemical properties. The synthetic route is as follows.
Example 71; 4-f [3-chloro-4-(pyridin-2-ylmethoxy)phenyl]amino) [1]benzothieno[2,3-d] pyrimidin-7-ol; Step 1. Preparation of 3-Chloro-4-(pyridin-2-ylmethoxy)-phenylamine; EPO 2-chloro-4-nitro phenol (10 g, 57.6 mmol, 1 equiv), 2-pycolyl chloride hydrogen chloride (9.45 g, 57.6 mmol, 1 equiv) cesium carbonate 41.3 (126.8 mmol, 2.2 equiv) and sodium iodide (8.64 g, 57.6 mmol, 1 equiv) were suspended in 200 mL acetonitrile. The reaction mixture was stirred at 60C for 5h. The resulted suspension was filtered and washed with water (400 mL), yielding 2-(2-chloro-4- nitro-phenoxymethyl)-pyridine (8 g, 52%) as a red solid.2-(2-chloro-4-nitro-phenoxyrnethyl)-pyridine (8 g, 30.2mmol, 1 equiv) and iron (8.44 g, 151.1 mmol, 5 equiv) were mixed in acetic acid (100 mL ) and EtOAc (50 mL ) and were stirred at rt overnight. The reaction mixture was filtered through a pad of Celite. The filtrate was concentrated in vacuo and neutralized with saturated Na2CO3 solution. The solution was extracted with EtOAc and the organic layer was washed with brine and concentrated in vacuo. The resulting crude material was purified by flash chromatography eluting with EtOAc/hexane (3:7) to give 3-Chloro- 4-(pyridin-2-ylmethoxy)-phenylamine (3.2 g, 52%) as a white solid. 1H-NMR (CDCl3) delta 5.18 (s, 2H), 6.50 (dd, 1H), 6.76 (d, 1H),. 6.80 (d, 1H), 7.22 (m, 1H), 7.64 (d, 1H), 7.73 (td, 1H), 8.55 (m, 1H); LCMS RT = 0.89 min, [M+H]+ = 235.1.
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 179687-79-7, 2-((2-Chloro-4-nitrophenoxy)methyl)pyridine.
