실험 절차

A stirred mixture of N-[3-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidiny]propoxyl]phenyl]acetamide (9.2 g, 22 mmol), prepared as described in the previous example, in 15% hydrochloric acid (110 ml) was heated at 100° C. for 2.5 hours until a homogeneous solution resulted. The reaction was cooled to 0° C. in an ice bath and basified with 50% NaOH. The product was extracted with ethyl acetate (3×200 ml). The ethyl acetate solution was washed with water, brine, then dried over Na2SO4. The solvent was removed. The crude product was purified on a flash chromatography column. The product thus obtained was a solid: 6.6 g (80%). Recrystallization from hot ethanol (50 ml) gave 3-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]propoxy]-aniline as off-white crystals: 3.46 g, m.p.=115°-117° C.
