Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 14508-49-7, name is 2-Chloropyrazine, This compound has unique chemical properties. The synthetic route is as follows., COA of Formula: C4H3ClN2
A mixture of chloropyrazine 3 (5.0 mmol) and HNR1R2 (10.0 mmol) was heated at 100 C. in a sealed tube for 15 h. The reaction mixture was cooled to room temperature, diluted with methylene chloride (50 mL), washed with saturated sodium bicarbonate solution (10 mL), dried over sodium sulfate and concentrated to provide the product 4, which could be purified by column chromatography, but was usually used in the next step without purification.; Prepared from 2-chloropyrazine and diethanolamine according to general procedure 2 providing the aminopyrazine (700 mg, quant.) as an oil; 1H NMR (300 MHz, CDCl3) delta 7.80-7.99 (dd, J=2.7, 1.5 Hz, 1H), 7.90-7.89 (d, J=1.5 Hz, 1H), 7.79-7.80 (d, J=2.8 Hz, 1H), 4.78 (br s, 1H), 2.80-2.79 (d, J=4.9 Hz, 3H).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 14508-49-7.
