Reaction Steps
A mixture of 3-(4-bromobutyl)-2,5,5-trimethyl-4-thiazolidinone (4.70 g), 1-(1,2-benzisothiazol-3-yl)piperazine 1-(1,2-benzisothiazol-3-yl)piperazine hydrochloride (4.72 g), K2CO3 (8.13 g) and NaI (300 mg) in acetonitrile (200 ml) was heated at 65° C. for 16 hours and the product was processed in substantially the same manner as in Example 10 to afford 2.77 g of crystals, m.p. 209°-214° C.
