Reaction Steps

PyBOP (3.5 g, 6.72 mmol) was added to a mixture of 5-carboxy-2-oxindole (1 g, 5.6 mmol), morpholine (0.5 mL, 6.2 mmol) and triethylamine (2.0 mL, 14 mmol) in dichloromethane. After stirring at room temperature for 4 hours, the reaction was diluted with more dichloromethane, washed with saturated sodium bicarbonate and brine, dried and concentrated. The residue was purified by column chromatography to give 5-(morpholine-4-carbonyl)-1,3-dihydro-indol-2-one.
