Related Products of 25109-86-8, A common heterocyclic compound, 25109-86-8, name is Methyl 2-(2-bromoethyl)benzoate, molecular formula is C10H11BrO2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Methyl 2-(2-(4-Chloro-2-nitrophenoxy)ethyl)benzoate To a solution of 4-chloro-2-nitrophenol (985 mg, 5.68 mmol) in DMF (10 ml) was added crude Intermediate 33 (1.38 g, 5.68 mmol) and K2CO3 (3.9 g, 28.4 mmol) and the reaction was stirred at 90 C. for 16 hours, diluted with H2O, and the resulting solution was extracted with EtOAc and washed with brine, dried over Na2SO4 and concentrated in vacuo, followed by MPLC purification to yield Intermediate 34 (520 mg, 27% for 2 steps). 1H NMR (600 MHz, CDCl3) delta 7.96 (dd, J=1.17, 7.92 Hz, 1H), 7.79 (d, J=2.64 Hz, 1H), 7.47-7.53 (m, 1H), 7.41-7.46 (m, 2H), 7.33 (td, J=1.17, 7.63 Hz, 1H), 7.07 (d, J=8.80 Hz, 1H), 4.39 (t, J=6.31 Hz, 2H), 3.91 (s, 3H), 3.49 (t, J=6.31 Hz, 2H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
