Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methylamine | HCID 6329 | — |
| Reactant | 2-oxo-2,3-dihydro-1H-indole-5-sulfonyl chloride | HCID 4962506 | — |
| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | N-methyl-2-oxoindoline-5-sulfonamide | HCID 10176909 | 88% |
Reaction Steps
A suspension of 3.38 g of 5-chlorosulfonyl-2-oxindole in 10 mL 2M methylamine in tetrahydrofuran was stirred at room temperature for 4 hours during which time a white solid formed. The precipitate was collected by vacuum filtration, washed twice with 5 mL of water and dried under vacuum at 40° C. overnight to give 3.0 g (88% yield) of 5-methylaminosulfonyl-2-oxindole.
