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. 37466-90-3, name is Ethyl 3,4-diaminobenzoate, This compound has unique chemical properties. The synthetic route is as follows., 37466-90-3
General procedure: Ethyl-3-amino-4-(2-substituted amino)benzoate, 3 (1 mmol) and various sodium bisulfite adducts, 4 (1.5 mmol) were dissolved in DMF (5 mL). The reaction mixture was stirred at 90 C under N2 atmosphere for 24-48 h. After completion of reaction (evident by TLC), the reaction mixture was diluted in ethyl acetate (25 mL) and washed with water (10 mL¡Á3). The organic layer was collected, dried over Na2SO4 and evaporated under reduced pressure to afford crude products. Final compounds 5-7 were obtained in 38-90% yields after recrystallization from ethanol or column purification.
