In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 77317-55-6 as follows. Formula: C8H8INO2
To a round bottom flask was added methyl 2-amino-5-iodobenzoate (5.00 g, 18.1 mmol) and di-tert-butyl dicarbonate (3.94 g, 18.1 mmol). The flask was sealed and evacuated/backfilled with nitrogen (3x) . Tetrahydrofuran (90 ml_) was added, and the reaction mixture was heated to 60 C overnight. 4-Dimethylaminopyridine (1.10 g, 9.02 mmol) was added, and the reaction mixture was heated for 1.5 hours. The reaction mixture was cooled to room temperature. Ethyl acetate and water were added, and the layers were separated . The organic layers were combined, dried over anhydrous sodium sulfate, filtered, and concentrated. Purification by flash column chromatography using ethyl acetate/hexanes as eluent provided the title compound as a pale yellow solid ( 1.70 g, 20%) : *H NMR (400 MHz, CDCI3) delta 8.32 (d, J = 2.1 Hz, 1H), 7.84 (dd, J = 8.3, 2.2 Hz, 1H), 6.93 (d, J = 8.3 Hz, 1H), 3.87 (s, 3H), 1.38 (s, 18H) ; EIMS m/z 478 ([M + H]+) .
According to the analysis of related databases, 77317-55-6, the application of this compound in the production field has become more and more popular.
