Uses | N,O-1, 3-diacetylindole is an organic intermediate, and it has been reported in the literature that it can be used to prepare 11-β-hydroxysteroid dehydrogenase Inhibitor. |
preparation | 2-[(carboxymethyl) amino] benzoic acid (intermediate -32) synthesis: to a 500mL double-neck RB flask equipped with a magnetic stirrer, to a stirring solution of K2CO3(83g,602mmol) in water (140mL) dropwise o-aminobenzoic acid (20g,145mmol), then chloroacetic acid (13.7g,145mmol) was added dropwise under N2 atmosphere at room temperature for about 30 minutes. The reaction material was then heated at 90°C for 16 hours. After the reactants are cooled to room temperature, the pH of the reaction material is adjusted to 4-5 using citric acid. The solid matter is then filtered and dried in a vacuum furnace at 70°C for 12 hours to produce an intermediate -32(23g) of a light brown solid. Synthesis of N,O-1,3-diacetylindole (intermediate -33): acetic anhydride (110mL,1200mmol) was slowly added to the stirring solution of triethylamine (170mL,1242mmol) and intermediate -32(23g,117mmol) under N2 atmosphere at 0 ℃ to a 500mL double-neck RB flask equipped with a magnetic stirred stirrer. The reaction material was stirred at room temperature for 5 hours and further heated at 80°C for 16 hours. The reactants were then cooled to 0°C and extracted with ethyl acetate (4 × 150mL). The organic layer was washed with a saline solution, dried and concentrated on Na2SO4. With hexane: EtOAc, the coarse material was purified by silica gel column elution to produce a brown solid intermediate -33(5.5g). |
