Reaction Steps
Dissolve methanesulfonic acid 3-{3-[4-(5-benzyloxybenzofur-7-yl)-2,5-dioxo-2,5-dihydro-1H-pyrrol-3-yl]indol-1-yl}propyl ester (220 mg, 0.39 mmol) and pyrrolidine (411 mg, 5.78 mmol) in 1-methylpyrrolidine (6 ml) and heat to 55° C. for 5 hours. Allow the reaction to cool to room temperature and stir overnight. Dilute the reaction in ethyl acetate, wash with water and brine, and dry with magnesium sulfate. Purification by flash chromatography gives the title compound (200 mg, 95%). MS(ES+): 546.13.
