Reaction Steps

In the same way as that described in Example 1, step 5, the title compound was prepared using spiro[indane-1,4'-piperidine] (77 mg, 0.41 mmol), DMF (10 ml), potassium carbonate (68 mg, 0.49 mmol), and n-butyl iodide (0.05 ml, 0.45 mmol). The crude residue was chromatographed using 5:95 methanol: dichloromethane, to give 1'-n-butylspiro[indane-1,4'-piperidine] (53 mg, 53%) as a beige solid.
