Synthetic Route of 58481-11-1, 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 58481-11-1, name is Methyl 2-chloroisonicotinate. This compound has unique chemical properties. The synthetic route is as follows.
Methyl 2-chloroisonicotinate (5.5 g, 32.05 mmol), (E)-4-fluorostyrylboronic acid (7.98 g, 48.08 mmol), potassium phosphate (3.93 mL, 48.08 mmol) and PdCl2 (dppf) (0.464 g, 0.64 mmol) were split into 5 equal portions and each portion was placed in a microwave reaction vessel. The vessels were evacuated and backfilled with nitrogen. Methanol (15 mL) was added to each vessel, the vessels were sealed and heated in a single node microwave reactor at 100° C. for 10 min each. The contents of the vessels was pooled and water and DCM were added, the phases separated and the aqueous layer was extracted with DCM. The combined organic layers were filtered through a phase separator and evaporated. The residue was purified by automated flash chromatography on a Biotage.(R). KP-SIL 340 g column. A gradient from 6:1 to 4:1 of EtOAc in heptane over 15 CV was used as mobile phase. (E)-Methyl 2-(4-fluorostyryl)isonicotinate (3.88 g, 47percent) was isolated. 1H NMR (400 MHz, cdcl3) delta 3.98 (s, 3H), 7.04-7.18 (m, 3H), 7.52-7.62 (m, 2H), 7.63-7.71 (m, 2H), 7.93 (s, 1H), 8.74 (d, 1H). MS m/z 258 (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 58481-11-1, Methyl 2-chloroisonicotinate.
