Application of 70298-89-4, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 70298-89-4, name is 2,2-Dimethyl-N-pyridin-4-yl-propionamide, molecular formula is C10H14N2O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
N-(Pyridin-4-yl)pivalamide (377 mg, 2.12 mmol) was dissolved in anhydrous tetrahydrofuran under inert atmosphere and cooled to – 78 °C. Within 1 h, a 1.6 M hexane solution of buthyl-lithium (3.3 mL, 5.29 mmol, 2.5eq) was added drop wise. Then the reaction mixture was warmed to 0 °C, stirred for 3 h, and anhydrous dimethylformamide (0.5 mL, 6.35 mmol, 3eq) in anhydrous tetrahydrofuran (3 mL) was added. Subsequently, the solution was warmed to room temperature and stirred for an additional 45 min. The mixture was poured onto a mixture of 6 N HCI (5 mL) and ice (5 g). After stirring for 5 min, the solution was neutralized with K2C03 (3.3 g) and extracted with diethylether. The organic layer was dried over MgS0 and the solvent was removed in vacuo. The residue was purified bycolumnchromatography to get N-(3-formylpyridin-4-yl)pivalamide (258 mg, 59 percent).
According to the analysis of related databases, 70298-89-4, the application of this compound in the production field has become more and more popular.
