Reaction Steps
A mixture of 3-(4-bromobutyl)-5-(2,2,2-trifluoroethyl)-4-thiazolidinone (3.20 g), 1-(1,2-benzisothiazol-3-yl)piperazine hydrochloride (2.81 g), K2CO3 (4.83 g) and NaI (250 mg) in acetonitrile (280 ml) was heated at 70° C. for 15 hours and the product was processed in substantially the same manner as in Example 10 to afford 2.30 g of crystals, m.p. 188°-200° C.
