Application of 1197294-80-6, 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 1197294-80-6, name is tert-Butyl 4-(4-bromopyridin-2-yl)piperazine-1-carboxylate. This compound has unique chemical properties. The synthetic route is as follows.
tert-Butyl 4-(4-bromopyridin-2-yl)piperazine-1-carboxylate (1.00 g, 2.66 mmol), 5-chloro-2-hydroxyphenylboronic acid (458 mg, 2.66 mmol) and sodium carbonate (1.13 g, 10.64 mmol) were combined and dissolved in a mixture of dioxane/water (14 mL/4 mL). The reaction mixture was degassed for 20 min with nitrogen and then tetrakistriphenylphosphinepalladium (0) (153 mg, 0.133 mmol) was added. The reaction mixture was heated at 70 C. for 18 hours and then partitioned between ethyl acetate (20 mL) and water (10 mL). The organic layer was separated, washed with brine (10 mL), dried over anhydrous MgSO4, filtered and concentrated in vacuo. The residue was purified on silica gel by Biotage (10% to 60% ethyl acetate in heptane over 20 CV) to give the title compound (700 mg, 66%) as a white solid.1H NMR (400 MHz, CD3OD): delta 1.40 (s, 9H), 3.50 (s, 8H), 6.80-6.90 (m, 2H), 6.95 (s, 1H), 7.15 (d, 1H), 7.30 (s, 1H), 8.05 (d, 1H).LCMS Rt=2.48 minutes MS m/z 388 [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 1197294-80-6, tert-Butyl 4-(4-bromopyridin-2-yl)piperazine-1-carboxylate.
