Reaction Steps
A mixture of 3-(4-bromobutyl)-5-methyl-4-thiazolidinone (4.00 g), 1-(1,2-benzisothiazol-3-yl)piperazine hydrochloride (4.46 g), K2CO3 (8.00 g) and NaI (300 mg) in acetonitrile (210 ml) was heated at 40°-45° C. for 64 hours and the product was processed in substantially the same manner as in Example 10 to afford 3.64 g of crystals, m.p. 113°-115° C.
