| Reactant | Sulfuric Acid | HCID 1118 | — |
| Reactant | 2-(Hydroxyimino)-N-[2-(propan-2-yl)phenyl]acetamide | HCID 71443947 | — |
| Product | 7-Isopropylindoline-2,3-dione | HCID 12272793 | 84% |
Reaction Steps
To concentrated sulfuric acid at 80° C. was added 2-hydroxyimino-N-(2-isopropyl-phenyl)-acetamide in several small portions over 10 minutes. After addition it was heated at 80° C. for 30 minutes., then poured into ice. Filtration, washing with water, and drying under vacuum over P2O5 provided 2.974 g (84%) of the title compound as a solid. ESI (−) MS m/e=188 (MH−).
