Reaktionsschritte

The title product was prepared following the procedure of example 41 from 7-trimethylstannyl-1-(4-methyl-1-piperazinyl)-naphthalene (0.25 g, 0.67 mmol), 3-methylsulfonylamino-1-bromobenzene (0.18 g, 0.72 mmol), triethylamine (0.45 mL, 3.23 mmol), lithium chloride (0.088 g, 2.07 mmol), and bis (triphenylphosphine) palladium chloride (0.025 g, 0.036 mmol) in DMF (12.5 mL) with a heating time of 1.5 hours. The product was obtained in 35% yield. A sample was obtained by recrystallization from ethyl acetate for analysis: mp 100°-101 ° C. Analysis calculated for C22H25N3O2S·1.5 H2O: C, 62.54; H, 6.68; N, 9.94. Found: C, 62.70; H, 6.46; N, 9.89.
