EXAMPLE 75; 5-[2-(4-BENZO[D]ISOTHIAZOL-3-YL-PIPERAZIN-1-YL)-ACETYL]- 1, 1, 3, 3-TETRAMETHYL-INDAN-2-ONE A mixture of 5- (2-Chloro-acetyl)-1, 1,3, 3-tetramethyl-indan-2-one (7.85 g, 29.6 mmol), 3-piperazin-1-yl-benzo[d]isothiazole hydrochloride (7.95 g, 31.1 mmol), potassium carbonate (13.5 g, 97.7 mmol), sodium iodide (4.50 g, 30.0 mmol) in acetonitrile (550 mL) was stirred at rt for 24 h. The reaction was quenched with water (120 mL), and acetonitrile was evaporated. The residue was extracted with methylene chloride (2 x 250 mL). The combined organic extracts were washed with water, brine, dried over Na2SO4, evaporated, and purified by chromatography (silica gel, 7: 3 to 6: 4 hexanes/ethyl acetate) to give 5-[2-(4-Benzo [agisothiazol-3-yl- piperazin-1-yl)-acetyl]-1, 1,3, 3-tetramethyl-indan-2-one (11.2 g, 85%) as an off-white solid :’H NMR (300 MHz, CDC13) 8 8.02 (dd, J= 8.0, 1.6 Hz, 1 H), 7.96 (s, 1 H), 7.91 (d, J = 8.0 Hz, 1 H), 7.83 (d, J = 8.0 Hz, 1 H), 7.47 (t, J = 7.0 Hz, 1 H), 7.38-7. 34 (m, 2H), 3.94 (br s, 2H), 3.67-3. 65 (m, 4H), 2.90- 2.88 (m, 4H), 1.38 (s, 6H), 1.37 (s, 6H).
With the complex challenges of chemical substances, we look forward to future research findings about 3-Piperazinobenzisothiazole hydrochloride
