실험 절차
A solution of 5-chlorosufonyl-2-oxindole (3 g) and 3-aminopyridine (1.46 g) in pyridine (15 mL) was stirred at room temperature overnight at which time a brown solid was present. The solid was filtered, washed with ethanol and dried under vacuum to yield 1.4 g (38%) of 2-oxo-2,3-dihydro-1H-indole-5-sulfonic acid pyridin-3-ylamide.
