المعالجة
- 1أخرىthe corresponding 3-diazoindol-2(3H)-one is prepared in accordance with known procedures
الإجراء التجريبي
Once the desired isatin has been obtained, the corresponding 3-diazoindol-2(3H)-one is prepared in accordance with known procedures. See, for example, J. M. Michowski, Tetrahedron Letters, 1773 (1967) and M. P. Cava, et al., J. Am. Chem. Soc., 80, 2257 (1958). The appropriate isatin compound is treated with p-toluenesulfonylhydrazine. The resulting hydrazone then is treated with a base such as aqueous sodium hydroxide or aluminum oxide to give the desired 3-diazoindol-2(3H)-one.
