87691-88-1, EXAMPLE 79 3-(4-(1-(1,2-Benzisothiazol-3-yl)-4-piperazinyl)butyl)-2-methyl-1-thia-3-azaspiro[4.4]nonan-4-one hydrochloride A mixture of 3-(4-bromobutyl)-2-methyl-1-thia-3-azaspiro[4.4]nonan-4-one (3.84 g), 1-(1,2-benzisothiazol-3-yl)piperazine hydrochloride (3.49 g), K2 CO3 (5.90 g) and NaI (280 mg) in acetonitrile (215 ml) was heated at between 65-80 C. for 16.5 hours and the product was processed in substantially the same manner as in Example 10 to afford 2.86 g of crystals, m.p. 210-215 C. ANALYSIS: Calculated for C23 H32 N4 OS2 *HCl: 57.42%C; 6.91%H; 11.64%N; 7.37%Cl. Found: 57.21%C; 6.87%H; 11.63%N; 7.03%Cl.
The synthetic route of 87691-88-1 has been constantly updated, and we look forward to future research findings.
