Electric Literature of 2077-19-2, 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. 2077-19-2, name is 2-(4-Bromophenyl)propan-2-ol. A new synthetic method of this compound is introduced below.
To a mixture of A-38 (2.80 g, 13.02 mmol) in THF (30 mL) was added NaH (1.04 g, 26.04 mmol, 60% purity) and CH3I (1.62 mL, 26.04 mmol) at 0 C and the mixture was stirred at 25 C for 16 hours. The mixture was quenched with a saturated solution of NH4C1 (50 mL), extracted with EtOAc (100 mL x 2), and the combined organic phase was washed with brine (30 mL), dried over Na2S04, filtered and concentrated to A-39 (2.70 g, 11.78 mmol) as an oil. 1H NMR (400MHz CDC13) _ = 7.47 (d, 2H), 7.29 (d, 2H), 3.07 (s, 3H), 1.51 (s, 6H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,2077-19-2, 2-(4-Bromophenyl)propan-2-ol, and friends who are interested can also refer to it.
