| Product | 5-(Morpholinosulfonyl)-2-oxindole | HCID 9795753 | 74.9% |
Reaction Steps
A suspension of 2.3 g of 5-chlorosulfonyl-2-oxindole from example O-18 and 2.2 g of morpholine in 50 mL of dichloromethane was stirred at room temperature for 3 hours. The white precipitate was collected by vacuum filtration, washed with ethyl acetate and hexane and dried under vacuum at 40° C. overnight to give 2.1 g (74% yield) of 5-(morpholin-4-sulfonyl)-2-oxindole.
