Reference of 52273-77-5, 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 52273-77-5, name is 2-(3-Aminophenyl)ethanol. This compound has unique chemical properties. The synthetic route is as follows.
Step B: 2-[3-({5-Chloro-4-[(3-methoxybenzyl)amino]pyrimidin-2-yl}amino)phenyl]ethanol Into a reaction flask were added 2,5-dichloro-N-(3-methoxybenzyl)pyrimidin-4-amine (0.33 g, 1.2 mmol) (prepared according to Example 1, step A), 1,4-dioxane (20 mL), 2-(3-aminophenyl)ethanol (0.22 g, 1.6 mmol), and p-toluenesulfonic acid monohydrate (0.080 g, 0.42 mmol). The mixture was heated at 105 C. for 3 hours and then an aqueous solution of NaHCO3 (saturated) was added. The organic solvent was removed under vacuum followed by the addition of water and EtOAc. The aqueous layer was extracted with EtOAc twice. The organic layers were combined, dried over Na2SO4, and concentrated under vacuum. The crude was purified by silica gel column chromatography to provide the desired product as a white solid (0.33 g, 74% yield). LCMS for C20H22ClN4O2 (M+H)+: m/z=385.1.
According to the analysis of related databases, 52273-77-5, the application of this compound in the production field has become more and more popular.
