Reaction Steps

Phosphorous oxychloride (1.93 mL, 3.17 mmol) is added slowly to a stirred solution of dimethylformamide (1.99 nmL) and dichloromethane (3 mL) cooled to 0-5° C. After 10 min, a solution of the above 1,3-dihydropyrrolo[2,3-b]pyridine-2-one hydrochloride (6-aza-1,3-dihydroindol-2-one) (790 mg, 4.63 mmol), pyridine (1.5 mL) and dichloromethane (5 mL) is added over 5 min and the reaction is stirred at room temperature for 18 hr. The solvents are removed to yield crude 3-dimethylaminomethylene-1,3-dihydropyrrolo[2,3-b]pyridin-2-one.
