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 153034-88-9, 2-Chloro-4-iodo-3-methylpyridine.

Synthetic Route of 153034-88-9, 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 153034-88-9, name is 2-Chloro-4-iodo-3-methylpyridine. This compound has unique chemical properties. The synthetic route is as follows.

A suspension of 2-chloro-4-iodo-3-methyl-pyridine (1.25 g, 4.88 mmol), acetic anhydride (2.31 mL, 24.5 mmol), lithium chloride (1.03 g, 24.2 mmol), Pd2(dba)3 (90 mg, 0.1 mmol), Hnig’s base (1.71 mL, 9.8 mmol) in DMF is heated at 160 0C in the microwave for 20 min. The reaction is partitioned between EtOAc and saturated NaHCOs(aq). The organics layer was collected and washed with brine, dried over Na2SO4 and stripped down in vacuo. The crude product is purified by silica column chromatography eluting with 20% EtOAc: Hexanes giving l-(2-chloro-3-methyl-pyridin-4-yl)-ethanone (408 mg, 2.41 mmol) as a clear oil. 1H NMR (400 MHz, CDCl3) delta 2.46 (s, 3H), 2.59 (s, 3H), 7.28 (d, IH), 8.36 (d, IH); MS m/z 170.2 (M + 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 153034-88-9, 2-Chloro-4-iodo-3-methylpyridine.
