실험 절차

A suspension prepared from 25.3 g (100 mmol) of the compound obtained in Step 1, 22.0 g (100 mmol) of (2,3-dihydro[1,4]benzodioxin-5-yl)piperazine, 13.8 g (100 mmol) of potassium carbonate and 140 ml of dimethylformamide is stirred at room temperature for 20 hours. The mixture is then poured into 1.5 liters of water, and the solid that forms (violet) is filtered off, rinsed with water and dried in vacuo to obtain 28.1 g of the expected product.
