Synthetic Route of 73583-41-2, 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 73583-41-2, name is 4-Bromo-3-chloropyridine. This compound has unique chemical properties. The synthetic route is as follows.
EXAMPLE 01-51 Preparation of 3-[(3-chloropyridin-4-yl)amino]-2-methylcyclohex-2-en-l-one (01-51): 3- amino-2-methylcyclohex-2-enone (500 mg, 4 mmol), 4-bromo-3-chloropyridine (950 mg, 5 mmol), palladium acetate (90 mg, 0.4 mmol), BINAP (197 mg, 0.8 mmol), cesium carbonate (2.6 g, 8 mmol) and toluene (10 mL) were combined in a sealed flask and heated at 100C, for 18 h. At rt, the mixture was filtered and the filtrate was diluted with EtOAc (30 mL), washed with brine (3 x 10 mL), dried with Na2S04. The crude was purified by HPLC to afford the title compound (140 mg, 15% yield, white microcrystal, mp = 135-138C). 1H NMR (D6-DMSO) delta 1.46 (s, 3H), 1.83-1.88 (m, 2H), 2.31 (t, J= 6.7 Hz, 2H), 2.53-2.57 (m, 2H), 6.84 (d, J= 6.1 Hz, 1H), 8.06 (s, 1H), 8.29 (d, J= 6.1 Hz, 1H), 8.48 (s, 1H). 13C NMR (D6-DMSO) delta 10.9, 20.6, 28.7, 36.7, 115.7, 117.1, 121.2, 144.7, 148.3, 148.3, 149.2, 154.4, 197.0. LCMS t = 1.9 min, m/z Calcd for Ci2Hi4ClN20; Ci2Hi3ClN2NaO 237.080; 259.061 [M+H]+; [2M+H]+, Found 237.080; 259.180.
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 73583-41-2, 4-Bromo-3-chloropyridine.
