Reaction Steps

Sodium sulfide (292 mg, 3.75 mmol) was added to a solution of 5-bromo-3,3-bis(2-bromoethyl)-1,3-dihydro-2H-indol-2-one from Step B (532 mg, 1.25 mmol) in DMF (2 mL) and the solution heated to 50° C. After 2.5 h, the mixture was partitioned between CH2Cl2 (20 mL) and H2O (20 mL). The layers were separated and the aqueous layer was further extracted with CH2Cl2 (2×10 mL). The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo to give the title compound. MS: m/z=300 (M+1).
