| Abstract: | The title compound was prepared from o nitroethylbenzene, a by product in the producing processes of chloromycetin, through nitration by mixed acid and hydrogenation reduction. Some factors influencing on the synthetic reactions were discussed, and the suitable conditions of the reactions were obtained by experiments. The yield of the nitration was 92.7 %,and that of the reduction was 98 %.The molecular structures of the product and its intermediate were elucidated by IR, NMR and MS. |
