Reference of 27489-62-9, 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. 27489-62-9, name is trans-4-Aminocyclohexanol. A new synthetic method of this compound is introduced below.
To a solution of trans-A- aminocyclohexanol (3 g, 26 mmol) in DMF (130 mL) at 0 C was added 60% sodium hydride in oil. The reaction mixture was stirred at 0 C for lh and then 4-fluorobenzonitrile (3.9 g, 32.6 mmol) was added. It was heated to 60 C for 2h and stirred for 12 h at room temperature. The reaction mixture was diluted with EtOAc and washed with water and brine. The organic layer was dried, filtered, and concentrated under reduced pressure to provide the titled compound (2.5 g, 44% yield). NMR (300 MHz, DMSO-c¾): 67.72 (d, J = 9 Hz, 2H), 7.09 (d, J = 9 Hz, 2H), 4.48-4.34 (m, 1H), 2.68-2.55 (m, 1H), 2.07-1.94 (m, 2H), 1.85-1.71 (m, 2H), 1.46-1.11 (m, 4H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,27489-62-9, its application will become more common.
