Abstract:HX-531 was synthesized through eight steps using 2-nitroaniline and 2-bromo-5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalene as the raw material. The structures of the target compound and key intermediates were confirmed by 1H NMR and MS spectra. The total yield reached 30%(calculated by 2-nitroaniline). Compared with the route reported in literatures, the improved process has several advantages such as reducing pollution, Saving raw materials, getting a higher yield. |
Key words:2-nitroaniline;2-bromo-5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalene; RXR antagonist; HX-531 |
