Reference of 2688-84-8, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 2688-84-8, name is 2-Phenoxyaniline, This compound has unique chemical properties. The synthetic route is as follows.
5.58.1 3-(2-Phenoxyphenylamino)phthalic acid dimethyl ester A mixture of 3-iodophthalic acid dimethyl ester (1.0 g, 3.1 mmol), 2-phenoxyaniline (0.57 g, 3.1 mmol), Pd2(dba)3 (0.13 g, 0.14 mmol), rac-BINAP (0.058 g, 0.093 mmol), and cesium carbonate (1.4 g, 4.3 mmol), in 6 mL toluene was heated to reflux under nitrogen for 24 hours. The reaction mixture was cooled, diluted with CH2Cl2 (10 mL), and filtered through Celite, and the filter was washed with additional CH2Cl2 (30 mL). The filtrate was evaporated, and the residue was chromatographed using a hexanes-ethyl acetate gradient, eluting 0.86 g of the product at 80:20 hexanes-ethyl acetate, in 73% yield: 1H NMR (CDCl3) delta 3.75 (s, 3H), 3.86 (s, 3H), 6.93-7.03 (m, 4H), 7.06-7.12 (m, 2H), 7.17 (dd, J=7.3 Hz, J=1.0 Hz, 1H), 7.29-7.38 (m, 4H), 7.46 (d, J=8.4 Hz, 1H), 7.89 (s, 1H).
The chemical industry reduces the impact on the environment during synthesis 2-Phenoxyaniline. I believe this compound will play a more active role in future production and life.
