Related Products of 946002-90-0, 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. 946002-90-0, name is (S)-1-(5-Bromopyridin-2-yl)pyrrolidin-3-ol. A new synthetic method of this compound is introduced below.
(S)-5-Bromo-2-(3-tert-butyl-dimethyl-silanyloxy)-pyrrolidin-l-yl)pyridine (G2). To a sol. of compound Gl (20.9 g, 85.8 mmol) in DMF (350 mL) at 0 0C were added imidazole (14.6 g, 215 mmol) and TBDMS-Cl (19.4 g, 129 mmol). This mixture was stirred at rt for 1.5 h, and aq. 10% K2CO3 (150 mL) was added. The mixture was extracted with heptane (2x). The combined org. extracts were dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Purification of the residue by FC (heptane/EtOAc 5 : 1 ? 4: 1 ? 3 : 1 ? 1 : 1) yielded the title compound (30.5 g, 99%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,946002-90-0, its application will become more common.
