Reaction Steps
A mixture of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole (6.44 g, 29.1 mmole), K2CO3 (6.4 g, 46 mmoles), N-(3-bromopropyl)phthalimide (8.4 g, 31 mmoles) in acetonitrile (150 ml) was heated at reflux for 3.5 hr. The insolubles were filtered. The solvent was removed at reduced pressure and the residue was purified by silica gel column chromatography to give N-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]propyl]phthalimide as a white solid. Recrystallization from ethanol yielded 9.8 g (83%) of off-white crystals, m.p.=129°-1300C.
