Participants

Reaction Steps

A mixture of 3.7 g of 4-benzamidopiperidine, 4.3 g of 3-(3-chloropropyl)-6-fluoro-1,2-benzisoxazole, 8 g of sodium bicarbonate and a few crystals potassium iodide in 30 ml of dimethylformamide was stirred at 55° C. for 2.5 hrs. The reaction mixture was cooled and concentrated to an oil. The oil was stirred with water and extracted with ether/ethyl acetate. The organic extracts were washed with water, saturated sodium chloride solution, dried over anhydrous magnesium sulfate, filtered and concentrated. Crystallization of the residue with isopropyl ether gave 1.2 g (17%) of product, mp 150°-151° C.
