The synthetic route is as follows., COA of Formula: C7H5ClF3N
General procedure: To a solution of 3-chloroaniline 5a (37mg, 0.33mmol) in H2O (10mL cooled to-5C) was added 0.2mL of 2N HCl (aq.). To the resulting acidic aniline solution, 1N solution of sodium nitrite (0.33mL, 0.33mmol) was added dropwise to generate the aryldiazonium salt solution 6a. To the aryldiazonium salt solution was added sodium acetate (54mg, 0.66mmol), followed by 1mL solution of crude 3-oxo-3-(3-phenylisoxazol-5-yl)propanenitrile 4a (88mg, 0.33mmol) in ethanol. The reaction mixture was stirred at 0C for 5min, and then poured onto H2O (10mL) and extracted with ethyl acetate (20mL). The organic layer was dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by short column chromatography on silica gel, eluting with hexane/ethyl acetate (2/1) to provide the desired product 7 (67mg, 50% for two steps from 3a) as a yellow solid.
According to the analysis of related databases, 69411-05-8, the application of this compound in the production field has become more and more popular.
