Adding a certain compound to certain chemical reactions, such as: 113421-98-0, name is 4-Fluoro-3-(trifluoromethoxy)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 113421-98-0, name: 4-Fluoro-3-(trifluoromethoxy)aniline
General procedure: Ethyl 4-bromo-1H-indole-2-carboxylate (1 eq), Pd2(dba)3 (0.1 eq), X-phos(0.2 eq), Cs2CO3 (3 eq) and aryl amine (3 eq) was added to a microwave tube,dissolved in 1,4-dioxane, and filled with argon gas. The microwave reaction wascarried out at 100 C for 0.5-1.5 h, and the starting material disappeared. The mixturewas cooled to room temperature and concentrated. Ethyl acetate was added todissolve the residue, and the mixture was washed with saturated brine and water, driedover anhydrous Na2SO4, and concentrated in vacuo. The crude product was purifiedby column chromatography to afford the target compound. Compounds 8m-8o, 8s,8a-3 ~ 8a-5, 8a-13, 8a-15 ~ 8a-17, 8o-1 ~ 8o-24 were prepared with method 3.
