Related Products of 951625-93-7, 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 951625-93-7, name is Methyl 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carboxylate. This compound has unique chemical properties. The synthetic route is as follows.
Synthesis of methyl 4-chloro-l-tosyl-lH-pyrrolo[2,3-b]pyridine-5-carboxylate:Sodium hydride (341 mg, 8.53 mol, 1.2 eq) was added in portions to a solution of methyl 4- chloro-lH-pyrrolo[2,3-b]pyridine-5-carboxylate (1.5 g, 7.1 mmol, 1.0 eq) in THF (20 mL). The suspension was stirred at 0 C for 30 min, then a solution of 4-methylbenzene-l-sulfonyl chloride (2.7 g, 14.2 mmol, 2.0 eq) in THF (10 mL) was added at 0 C. The resulting suspension was stirred at this temperature for 15 min and 1 h at room temperature. The suspension was filtered through Celite. The filtrate was diluted with EtOAc (200 mL), washed with brine (100 mL x 3). The combined organic layer was dried (MgS04) and concentrated in vacuo to afford a residue which was purified by silica gel column chromatography (PE/EA = 10:1) to give 128.5 a white solid (1.6 g, yield: 60%). XH NMR (400 MHz, DMSO-J6) delta: 8.84 (s, 1H), 8.12 (d, 1H), 8.06 (d, 2H), 7.46 (d, 2H), 6.98 (d, 1H), 3.93 (s, 3H), 2.39 (s, 3 H). ESI-MS: 365.0 (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 951625-93-7, Methyl 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carboxylate.
