Related Products of 170235-18-4, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 170235-18-4 as follows.
(1) 3-(trifluoromethyl) phenol (1.317 g, 0.0081 mol) was dissolved in 10 ml of dried dimethyl acetamide. While cooling the obtained solution with water, sodium hydride (0.39 g (ca. 60% in mineral oil), 0.0081*1.2 mol) was added to the solution. After completion of the foaming, a solution obtained by dissolving 6-bromo-5-methoxy-2-pyridine carboxylic acid methyl ester (2.0 g, 0.0081 mol) in 10 ml of dried dimethyl acetamide, and then copper iodide (1.55 g, 0.081 mol) were successively added to the solution. The obtained mixture was heated and stirred at 120 C. for 10 hours. Thereafter, the obtained reaction solution was cooled, mixed with 50 ml of water and then with 50 ml of ethyl acetate, and filtered through a glass filter provided with Hyflo Super-Cell. The obtained filtrate was extracted with ethyl acetate to obtain an aimed product. An organic phase was separated from the product, washed with water and then dried with anhydrous sodium sulfate. The dried product was concentrated, and the obtained residues were purified by silica gel column chromatography (eluding solution: ethyl acetate/hexane). Yield weight: 0.68 g; yield percentage: 26%; solid; melting point: 116 to 118 C.; 1 H-NMR (60 MHz, CDCl3, delta): 3.76(3H, s), 3.86(3H, s), 7.16(1H, d, J=8 Hz), 7.2-7.5(4H, complex), 7.80(1H, d, J=8 Hz).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,170235-18-4, its application will become more common.
