実験手順

A mixture of N-(4-bromobutyl)-3,3-dimethylglutarimide (4 g., 0.0145 mole) obtained according to the procedure of Example 9, 3-(1-piperazinyl)-1,2-benzisothiazole (3.18 g., 0.0145 mole), anhydrous potassium carbonate (20.04 g., 0.145 mole) and potassium iodide (0.25 g., 0.0015 mole) in 150 ml. of acetonitrile is stirred and refluxed for a period of 12 hr. The reaction mixture is filtered, concentrated in vacuo and residual material triturated with ether. Crystallization of the solid thus obtained from ether affords a 64% yield of analytically pure 1-[4-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]butyl]-4,4-dimethyl-2,6-piperidinedione, m.p. 146°-147° C.
