실험 절차

A stirred mixture of 6-fluoro-3-(4-piperidinyl)-1,2 benzisoxazole hydrochloride (5.1 g, 20 mmol), K2CO3 (5.2 g, 40 mmol), 1-[4-(3-chloropropoxy)-3-methoxyphenyl]-ethanone (5.3 g, 22 mmol), and dimethylformamide (60 ml) was heated at 90° C. for 16 hours. The reaction was poured into water, and the aqueous mixture was extracted with ethyl acetate. The ethyl acetate was washed (water), dried (MgSO4) and concentrated to afford a moist solid. Recrystallization (twice) from ethyl alcohol afforded 5.0 g (58%) of 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]-propoxy]-3-methoxyphenyl]-ethanone as a beige solid, m.p.=118°-120° C.
