Research on new synthetic routes about C9H9IO2

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.

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. 58313-23-8, name is Ethyl-3-iodobenzoate, A new synthetic method of this compound is introduced below., Recommanded Product: Ethyl-3-iodobenzoate

To a solution of {l-{[(l,l-dimethylethyl)oxy]carbonyl}-5-[(phenylmethyl)oxy]-lH- indol-2-yl}boronic acid (1.13 g, 3.08 mmol), ethyl-3-iodobenzoate (0.34 mL, 2 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.126 g, 0.11 mmol), in 1,2- dimethoxyethane (35 mL) was added sodium carbonate (2 M) (4 mL, 8 mmol). The stirred reaction mixture was heated at reflux for 4 h under a nitrogen atmosphere. The reaction mixture was allowed to cool at room temperature and partitioned between water and ethyl acetate. The organic phase was separated, dried over magnesium sulfate, filtered, and the filtrate was concentrated to give an oil. The crude product was purified by flash chromatography over silica with a hexanes: ethyl acetate gradient (100:0 to 70:30) to give an oil. The oil was dissolved in dichloromethane and the solution was concentrated to give the product. The product was dissolved in ethyl acetate and one-half of the solution was concentrated to give 0.42 g of 1,1- dimethylethyl 2- {3-[(ethyloxy)carbonyl]phenyl} -5-[(phenylmethyl)oxy]- lH-indole- 1 – carboxylate for a total yield of 0.84 g (89%). 1U NMR (400 MHz, DMSO-J6): delta 7.99 (d, J = 9 Hz, IH), 7.95 (m, 2H), 7.75 (d, J = 8 Hz, IH), 7.58 (t, J = 8 Hz, IH), 7.45 (m, 2H), 7.37 (m, 2H), 7.31 (m, IH), 7.21 (d, J = 3 Hz, IH), 7.03 (dd, J = 9, 3 Hz, IH), 6.72 (s, IH), 5.13 (s, 2H), 4.32 (q, J = 7 Hz, 2H), 1.30 (t, J = 7 Hz, 3H), 1.23 (s, 9H). ES-LCMS m/z 494 (M + Na)+.
