Application of 13466-38-1, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 13466-38-1, name is 5-Bromopyridin-2-ol. A new synthetic method of this compound is introduced below.
Example 142 To a solution of 5-bromopyridin-2-ol (1.0 g, 5.75 mmol) in DMF (10 mL) at RT, potassium tert-butoxide (0.68 g, 6.07 mmol) was added and the mixture was stirred for 30 min. To this mixture, (bromomethyl)cyclopropane (1.03 g, 8.62 mmol) was added, and the resulting mixture was stirred at 70 C. for 2 h. The mixture was allowed to cool to RT, diluted with EtOAc (50 mL) and quenched with water (20 mL). The organic layer was washed with water (2*20 mL) and brine (20 mL), dried over anhydrous MgSO4 and filtered. The filtrate was concentrated in vacuo to afford 5-bromo-1-(cyclopropylmethyl)pyridin-2(1H)-one. 1-(Cyclopropylmethyl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one was prepared in analogous fashion to Example 140, except 5-bromo-1-(cyclopropylmethyl)pyridin-2(1H)-one was used in place of 5-bromo-1-ethylpyridin-2(1H)-one. Compound 232 was prepared from compound 8 in analogous fashion to Example 140, except 1-(cyclopropylmethyl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one was used in place of 1-ethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one. ESI-MS m/z: 530.3 [M+H]+.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,13466-38-1, its application will become more common.
