Adding a certain compound to certain chemical reactions, such as: 22236-10-8, name is 4-(Difluoromethoxy)aniline, 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 22236-10-8, Formula: C7H7F2NO
Example 2 3- { [4- (DIFLUOROMETHOXY) PHENYL] AMINO}-1- (2-METHOXYETHYL)-4-PHENYL-LH-PYRROLE-2, 5- dione 3-CHLORO-1-(2-METHOXYETHYL)-4-PHENYL-LH-PYRROLE-2, 5-dione (0.13 mmol, 36 mg) AND 4- difluoromethoxyaniline (0.28 mmol, 45 mg) were dissolved in DMF (1 mL). The mixture was heated in a microwave reactor at 150C for 20 min.. After cooling, the reaction mixture was purified by HPLC (95% 0. 1M ammonium acetate buffer: 5% CH3CN No. 100% CH3CN) to give 13 mg (24%) of the title COMPOUND. 1H NMR (400 MHz, CDC13) : 8 7.25 (bs, 1H), 7.19-7. 08 (m, 3H), 7.02-6. 97 (m, 2H), 6.81-6. 75 (m, 2H), 6.66-6. 60 (m, 2H), 6.36 (t, J=74.0 Hz, 1H), 3. 83 (t, J=5.7 Hz, 2H), 3.63 (t, J=5.7 Hz, 2H), 3. 38 (s, 3H)
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-(Difluoromethoxy)aniline, and friends who are interested can also refer to it.
