Synthetic Route of 886365-46-4, 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 886365-46-4, name is 5-Chloro-3-methylpyridine-2-carboxylic acid. This compound has unique chemical properties. The synthetic route is as follows.
Crude tert-butyl ((4aRS,11bRS)-10-amino-3,3,11b-trimethyl-4,4-dioxido-4-a,5,6,11b-tetrahydro-3H-benzo[6,7]oxepino[4,5-b][1,4]thiazin-2-yl)carbamate (70 mg, 0.165 mmol) was suspended in DMF (2 ml) and sonicated for 1 min. 5-Chloro-3-methylpyridine-2-carboxylic acid (34.0 mg, 0.198 mmol), pyridine (0.04 ml, 0.496 mmol) and HATU (94 mg, 0.248 mmol) were added and resulting suspension was stirred for 45 min at RT. The mixture was diluted with EtOAc (8 ml) and saturated NaHCO3 solution (3 ml). Water was added to dissolve precipitated solids. The organic layer was separated, washed with water and concentrated, and the resulting concentrate/residue was purified by FC on 12 g RediSep Gold column using 10-80% EtOAc in heptane to afford tert-butyl ((4aRS,11bRS)-10-(5-chloro-3-methylpicolinamido)-3,3,11b-trimethyl-4,4-dioxido-4-a,5,6,11b-tetrahydro-3H-benzo[6,7]oxepino[4,5-b][1,4]thiazin-2-yl)carbamate (76 mg, 0.132 mmol, 80% yield) as white solid.
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 886365-46-4, 5-Chloro-3-methylpyridine-2-carboxylic acid.
