実験手順

A mixture of 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-piperidinyl]propoxy]-3-methoxyphenyl]ethanone (4.3 g, 10 mmol), prepared as in Example 3 above, hydroxylamine hydrochloride (1.3 g, 18 mmol), ammonium acetate (1.7 g, 22 mmol) and ethanol-H2O was stirred and refluxed for 16 hours. The reaction was poured into water, and the mixture was cooled in an ice bath for 2 hours. The resultant, white solid was collected washed with water, and dried to yield 4,6 g or hydrochloride salt of the oxime, m.p.=216°-218° C. The compound was dispersed in water, and ammonium hydroxide was added until the suspension was decidedly basic. The basic suspension was then extracted with dichloromethane, and after washing with water, drying (MgSO4) and concentrating the extract, 3.0 g of white solid melting at 168°-170° C. were harvested. The compound, was recrystallized from dimethylformamide to yield 2.3 g (52%) of 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-1-piperidinyl]propoxy]-3-methoxyphenyl]ethanone oxime as a white solid, m.p.=168°-170° C. ANALYSIS: Calculated for C24H28FN3O4: 65.29%C 6.39%H 9.52%N Found: 65.27%C 6.44%H 9.46%N
