The synthetic route is as follows., Computed Properties of C8H8N2O2
General procedure: We described the synthesis of the compound 1 (Table 2) to illustrate the general procedure for TFA accelerated Petasis three-component reaction. The descriptions of the preparations of all reported compounds are in the Supporting information section. To a magnetically stirred mixture of 5-nitroindoline (0.164 g, 1.0 mmol), 4-tolyboronic acid (0.135 g, 1.0 mmol), and glyoxylic acid monohydrate (0.092 g, 1.0 mmol) in CH2Cl2 (5 ml) was added TFA (20 mul). The mixture was stirred at room temperature for 4 h. After the completion of the reaction (TLC monitoring), half of the solvent was evaporated by means of a rotovap. The resulting solid was filtered through a sintered glass funnel. The collected solid was thoroughly washed with petroleum ether and a small amount of ice water (5 ml), and then dried in vacuo at room temperature for 24 h to afford 0.26 g (83.3 %) of 2-(5-nitroindolin-1-yl)-2-(p-tolyl) acetic acid as a light yellow solid.
According to the analysis of related databases, 32692-19-6, the application of this compound in the production field has become more and more popular.
