Reaction Steps

Methyl iodide (130.6 mg, 0.92 mmol) was added to a solution of 4-piperidin-4-yl-1,3-dihydroindol-2-one (199 mg, 0.92 mmol) in acetonitrile (10 mL) and methanol (1 mL). The reaction was stirred at room temperature under nitrogen for 2 days. The solvents were removed and the residue was purified on a silica gel column to give 150 mg (70%) of 4-(1-methylpiperidin-4-yl)-1,3-dihydroindol-2-one as a tan solid.
