Adding a certain compound to certain chemical reactions, such as: 1462-37-9, name is ((2-Bromoethoxy)methyl)benzene, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 1462-37-9, Formula: C9H11BrO
Methyl 1-(2-(benzyloxy)ethyl)-3-cyclohexyl-1H-indole-6-carboxylate. Intermediate 4 (1.029 g, 4.0 mmol) was added to a suspension of NaH (192 mg of 60percent dispersion in mineral oil, 4.8 mmol) in DMF (5 mL). The reaction mixture was stirred at room temperature for 15 minutes, treated with benzyl 2-bromoethyl ether (0.7 mL, 4.4 mmol), stirred at room temperature for 2 hours, quenched with water, and extracted with ethyl acetate (2.x.50 mL). The organic layers were combined and washed (1N HCl), dried (MgSO4), filtered, and concentrated. The residue was purified by flash column chromatography (silica gel, 3:1 hexanes/ethyl acetate) to provide the desired product as a colorless thick oil (1.19 g, 76percent yield). MS m/z 392(MH+); 1H NMR (500 MHz, CDCl3) delta 1.31 (m, 1H), 1.45 (m, 4H), 1.80 (d, J=13.12 Hz, 1H), 1.87 (m, 2H), 2.10 (m, 2H), 2.84 (m, 1H), 3.79 (t, J=5.34 Hz, 2H), 3.94 (s, 3H), 4.33 (t, J=5.49 Hz, 2H), 4.45 (s, 2H), 7.12 (s, 1H), 7.20 (m, 2H), 7.27 (m, 3H), 7.66 (d, J=8.55 Hz, 1H), 7.78 (d, J=8.55 Hz, 1H), 8.08 (s, 1H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, ((2-Bromoethoxy)methyl)benzene, and friends who are interested can also refer to it.
