実験手順

A mixture of 2 g of the product of Example 1 in 40 ml of dimethylformamide, 3.39 g of potassium carbonate and 1.6 ml of propyl iodide was stirred under inert atmosphere for 90 minutes. After adding water, extracting with methylene chloride, washing with water, drying, evaporating to dryness under reduced pressure and purifying the residue by chromatography over silica (eluent: methylene chloride--methanol 9-1), 1.6 g of 1,3-dihydro-7-methoxy-4-(1-propyl-3-piperidinyl)-2H-indol-2-one melting at ≈120° C. were obtained.
