With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.87691-88-1,3-Piperazinobenzisothiazole hydrochloride,as a common compound, the synthetic route is as follows.,87691-88-1

EXAMPLE 80 3-(4-(1-[1,2-Benzisothiazol-3-yl]-4-piperazinyl)butyl)1-thia-3-azaspiro[4.5]decan-4-one A mixture of 3-(4-bromobutyl)-1-thia-3-azaspiro[4.4]nonan-4-one (4.00 g), 1-(1,2-benzisothiazol-3-yl)piperazine hydrochloride (3.67 g), K2 CO3 (7.00 g) and NaI (300 mg) in acetonitrile (220 ml) was heated at 70 C. for 20 hours and the product was processed in substantially the same manner as in Example 10 to afford 3.01 g of crystalline solid, m.p. 209 C. ANALYSIS: Calculated for C23 H32 N4 OS2 ¡¤HCl: 57.42%C; 6.91%H; 11.64%N; 7.37%Cl. Found: 57.51%C; 6.82%H; 11.75%N; 7.30%Cl.

The synthetic route of 87691-88-1 has been constantly updated, and we look forward to future research findings.
